net/bnxt: restore MAC filters during reset recovery

Older Firmware could have state information such as
MAC Filters, VLAN settings etc configured by user.
But new Firmware is unaware of this state information
and as a result driver should restore these settings
during reset recovery.

This patch restores the user configured mac addresses
prior to hot FW upgrade or FW error.
