rfkill: fix led-trigger unregister order in error unwind
rfkill needs to unregister the led trigger AFTER a call to
rfkill_remove_switch(), otherwise it will not update the LED state,
possibly leaving it ON when it should be OFF.
To make led-trigger unregistering safer, guard against unregistering a
trigger twice, and also against issuing trigger events to a led trigger
that was unregistered. This makes the error unwind paths more resilient.
Refer to "rfkill: Register LED triggers before registering switch".
