[PATCH 4/7] net/bnxt: cleanup vnic ref count

[Ajit Khaparde]

From: Damodharam Ammepalli <damodharam.ammepa...@broadcom.com>

Cleanup vnic ref count when port is stopped.
When vlan strip is set/unset the current active
vnics are destroyed and recreated with VNIC id
provided by firmware. The default vnic at index 0
still has ref_cnt=1 while rx_queues are reset to 0,
which fails the check under bnxt_vnic_rss_action_free()

Resetting the vnic->ref_cnt in bnxt_free_all_hwrm_resources()
post FW handshake in clean-up path.
