net/mlx5: fix SSE Rx support verification

Browse Source 
The number of queues in DPDK does not means that the array of queue will be
totally filled, those information are uncorrelated.  The number of queues
is provided in the port configuration whereas the array is filled by
calling tx/rx_queue_setup().  As this number of queue is not increased or
decrease according to tx/rx_queue_setup() or tx/rx_queue_release(), PMD
must consider a queue may not be initialised in some position of the array.
