From: Rahul Gupta <rahul.gupta@broadcom.com>

During port 0 rxq 1 start ie queue start,
bnxt_free_hwrm_rx_ring() we are clearing the pointers to mbuf array.
Due to this we overwrite the queue with fresh mbuf allocations
causing previously allocated mbufs to leak.
Add a check before allocating mbuf to replenish only empty mbuf slots
in the RxQ.

bnxt_free_one_vnic and bnxt_setup_one_vnic are called on configuring
port vlan stripping. bnxt_setup_one_vnic keeps incrementing the
vnic rx_queue_cnt. Fix to reset vnic rx_queue_cnt in bnxt_free_one_vnic.
