examples/power: fix ack for enable/disable turbo

When a VM sends a command through virtio-serial to enable/disable
turbo, it is successfully enabled or disabled, yet the response to the
VM is NACK. This is because all the library frequency change APIs return
1 for success (change in frequency), 0 for success (no change in
frequency) and -1 for failure. However the turbo enable/disable APIs just
return 0 for success and -1 for failure.

Fix the handling of the return code to treat ">= 0" as success, and
send an ACK. Only send NACK when < 0 (failure).

vhost: catch overflow causing mmap of size 0

This patch catches an overflow that could happen if an
invalid region size or page alignment is provided by the
guest via the VHOST_USER_SET_MEM_TABLE request.

If the sum of the size to mmap and the alignment overflows
uint64_t, then RTE_ALIGN_CEIL(mmap_size, alignment) macro
will return 0. This value was passed as is as size argument
to mmap().

While kernel handling of mmap() syscall returns an error
if size is 0, it is better to catch it earlier and provide
a meaningful error log.

vhost: flush shadow Tx if no more packets

The current implementation of vhost_net in packed vring tries to fill
the shadow vector before send any actual changes to the guest. While
this can be beneficial for the throughput, it conflicts with some
bufferfloats methods like the linux kernel napi, that stops
transmitting packets if there are too much bytes/buffers in the
driver.

To solve it, we flush the shadow packets at the end of
virtio_dev_tx_packed if we have starved the vring, i.e. the next
buffer is not available for the device.

Since this last check can be expensive because of the atomic, we only
check it if we have not obtained the expected "count" packets. If it
happens to obtain "count" packets and there is no more available
packets the caller needs to keep call virtio_dev_tx_packed again.

vhost: do not treat empty socket message as error

According to recvmsg() specification, 0 is a valid
return code when client is disconnecting.
Therefore, it should not be reported as error, unless there
are other dependencies that require message to not be empty.
But there are none, since the next immediate caller of recvmsg()
reports "vhost peer closed" info (not error) when message is empty.

This patch changes return code check for recvmsg() so that
misleading error message is not printed when the code is 0.

vhost: fix crash on port deletion

The vhost_user_read_cb() and rte_vhost_driver_unregister()
can be called at the same time by 2 threads. Eg thread1
calls vhost_user_read_cb() and removes the vsocket from
conn_list, then thread2 calls rte_vhost_driver_unregister()
and frees the vsocket since it is NOT in the conn_list.
So thread1 will access invalid memory when trying to
reconnect.

The fix is to move the "removing of vsocket from conn_list"
to end of the vhost_user_read_cb(), then avoid the race
condition.

The core trace is:
Program terminated with signal 11, Segmentation fault.
