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 :-).
