rfkill: always call get_state() hook on resume
We "optimize" away the get_state() hook call on rfkill_toggle_radio
when doing a forced state change. This means the resume path is not
calling get_state() as it should.
Call it manually on the resume handler, as we don't want to mess with
the EPO path by removing the optimization. This has the added benefit
of making it explicit that rfkill->state could have been modified
before we hit the rfkill_toggle_radio() call in the class resume
handler.
