eth: bnxt: fix out-of-range access of vnic_info array
The bnxt_queue_{start | stop}() access vnic_info as much as allocated,
which indicates bp->nr_vnics.
So, it should not reach bp->vnic_info[bp->nr_vnics].
Fixes: 661958552eda ("eth: bnxt: do not use BNXT_VNIC_NTUPLE unconditionally in queue restart logic")
