rfkill: do not allow userspace to override ALL RADIOS OFF
SW_RFKILL_ALL is the "emergency power-off all radios" input event. It must
be handled, and must always do the same thing as far as the rfkill system
is concerned: all transmitters are to go *immediately* offline.
For safety, do NOT allow userspace to override EV_SW SW_RFKILL_ALL OFF. As
long as rfkill-input is loaded, that event will *always* be processed, and
it will *always* force all rfkill switches to disable all wireless
transmitters, regardless of user_claim attribute or anything else.
