refresh the corresponding scancode filter, i.e. try and set the same
scancode filter with the new protocol. If that fails clear the filter

If no protocol was selected the filter is just cleared, and if no
s_filter callback exists the filter is left unmodified.

Similarly clear the filter mask when the filter is set if no protocol is

This simplifies driver code which no longer has to explicitly worry
about modifying the filter on a protocol change. This also allows the
