eth: fbnic: take netif_addr_lock_bh() around rx mode address programming

When __fbnic_set_rx_mode() is called from contexts other than
.ndo_set_rx_mode_async(), the uc and mc addr lists are accessed
without the addr lock that __hw_addr_sync_dev() and
__hw_addr_unsync_dev() require. Wrap these unprotected accesses with
netif_addr_lock_bh(). fbnic_clear_rx_mode() has similar issues.
