[ Upstream commit
c0e01eac7ada785fdeaea1ae5476ec1cf3b00374 ]
In case we got an FDB notification for a port that doesn't exist we
execute an FDB entry delete to prevent it from re-appearing the next
time we poll for notifications.
If the operation failed we would trigger a NULL pointer dereference as
'mlxsw_sp_port' is NULL.
Fix it by reporting the error using the underlying bus device instead.
