Similarly clear the filter mask when the filter is set if no protocol is
currently selected.

This simplifies driver code which no longer has to explicitly worry
about modifying the filter on a protocol change. This also allows the
change_wakeup_protocol callback to be omitted entirely if there is only
a single available wakeup protocol at a time, since selecting no
