firmware: arm_sdei: Remove while loop in sdei_event_unregister()
This removes the unnecessary while loop in sdei_event_unregister()
because of the following two reasons. This shouldn't cause any
functional changes.
* The while loop is executed for once, meaning it's not needed
in theory.
* With the while loop removed, the nested statements can be
avoid to make the code a bit cleaner.
