sfc: fix addr_list_lock spinlock use before init
Reported by Nikolay Aleksandrov. In efx_init_port() we call
efx_mac_reconfigure() to work around a Falcon/A1 limitation, and this calls
efx_{arch}_filter_sync_rx_mode(), which takes the addr_list_lock; but this
lock is uninitialised, because we haven't called register_netdevice() yet.
So, in efx_farch_filter_sync_rx_mode(), check efx_dev_registered() before
doing anything else.
The EF10 equivalent, efx_ef10_filter_sync_rx_mode(), already has the
corresponding check.
