Lance Richardson e5f2b3ebcb net/bnxt: avoid unnecessary work in AVX2 Rx 
Each call to the AVX2 vector burst receive function makes at
least one pass through the function's inner loop, loading
256 bytes of completion descriptors and copying 8 rte_mbuf
pointers regardless of whether there are any packets to be
received.

Unidirectional forwarding performance is improved by about
3-4% if we ensure that at least one packet can be received
before entering the inner loop.

Fixes: c4e4c18963 ("net/bnxt: add AVX2 RX/Tx")
