crypto/aesni_mb: fix possible array overrun
In order to process crypto operations in the AESNI MB PMD,
they need to be sent to the buffer manager of the Multi-buffer library,
through the "job" structure.
Currently, it is checked if there are outstanding operations to process
in the ring, before getting a new job. However, if there are no available
jobs in the manager, a flush operation needs to take place, freeing some
of the jobs, so it can be used for the outstanding operation.
In order to avoid leaving the dequeued operation without being processed,
the maximum number of operations that can be flushed is the remaining
operations to return, which is the maximum number of operations that can
be return minus the number of operations ready to be returned
(nb_ops - processed_jobs), minus 1 (for the new operation).
The problem comes when (nb_ops - processed_jobs) is 1 (last operation to
dequeue). In that case, flush_mb_mgr is called with maximum number of
operations equal to 0, which is wrong, causing a potential overrun in the
"ops" array.
Besides, the operation dequeued from the ring will be leaked, as no more
operations can be returned.
The solution is to first check if there are jobs available in the manager.
If there are not, flush operation gets called, and if enough operations
are returned from the manager, then no more outstanding operations get
dequeued from the ring, avoiding both the memory leak and the array
overrun.
If there are enough jobs, PMD tries to dequeue an operation from the ring.
If there are no operations in the ring, the new job pointer is not used,
and it will be used in the next get_next_job call, so no memory leak
happens.

* As of MUSDK 18.09, pp2_cookie_t is no longer available. Now
RX descriptor cookie is defined as plain u64 so existing cast
is no longer valid.
* MUSDK 18.09 increased number of available bpools (buffer hw pools) by
introducing dma regions support. Update mvpp2 driver accordingly.
* replace MV_NET_IP4_F_TOS with MV_NET_IP4_F_DSCP
Before this patch, API allowed to configure a classification rule
according to IPv4 TOS, which was not supported in classifier. This patch
fixes this by using proper field.

read leaves less than this number available, a read from the next slave

results in skipping over that slave as the next active slave.
