rfkill: rfkill_set_block() when suspended nitpick
If we return after fiddling with the state, userspace will see the wrong state and rfkill_set_sw_state() won't work until the next call to rfkill_set_block(). At the moment rfkill_set_block() will always be called from rfkill_resume(), but this will change in future. Also, presumably the point of this test is to avoid bothering devices which may be suspended. If we don't want to call set_block(), we probably don't want to call query() either :-).
