[dpdk-stable] [PATCH 19.11 1/2] net/bnxt: fix MAC address setting when port is stopped

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

[upstream commit 1009a632c851f687b7f6ccf64875552afbac5c46 ]

Driver destroys the VNIC when the port is brought down.
Port HW filter setting such as default MAC address and
unicast MAC filters will be applied when port is started.

Fixed to return success silently for these callbacks
when port is stopped.

Fixes: 39b88344e364 ("net/bnxt: fix enable/disable VLAN filtering")
