vfio: fix interrupts race condition

Populating the eventfd in rte_intr_enable in each request to vfio
triggers a reconfiguration of the interrupt handler on the kernel side.
The problem is that rte_intr_enable is often used to re-enable masked
interrupts from drivers interrupt handlers.

This reconfiguration leaves a window during which a device could send
an interrupt and then the kernel logs this (unsolicited from the kernel
point of view) interrupt:
[158764.159833] do_IRQ: 9.34 No irq handler for vector

VFIO api makes it possible to set the fd at setup time.
Make use of this and then we only need to ask for masking/unmasking
legacy interrupts and we have nothing to do for MSI/MSIX.

hash: load value after full key compare

When a hash entry is added, there are 2 sets of stores.

1) The application writes its data to memory (whose address
is provided in rte_hash_add_key_with_hash_data API (or NULL))
2) The rte_hash library writes to its own internal data structures;
key store entry and the hash table.

The only ordering requirement between these 2 is that - store
to the application data must complete before the store to key_index.
There are no ordering requirements between the stores to
key/signature and store to application data. The synchronization
point for application data can be any point between the 'store to
application data' and 'store to the key_index'. So, 'pdata' should not
be a guard variable for the data in hash table. It should be a guard
variable only for the application data written to the memory location
pointed by 'pdata'. Hence, in the lookup functions, 'pdata' can be
loaded after full key comparison succeeds.

The synchronization point for the application data (store-release
to 'pdata' in key store) is changed to be consistent with the order
of loads in lookup function. However, this change is cosmetic and
does not affect the functionality.
