[PATCH net-next 07/14] devlink: drop the filter argument from devlinks_xa_find_get

Looks like devlinks_xa_find_get() was intended to get the mark
from the @filter argument. It doesn't actually use @filter, passing
DEVLINK_REGISTERED to xa_find_fn() directly. Walking marks other
than registered is unlikely so drop @filter argument completely.
