input: evdev: Move wake_lock_destroy call

Calling wake_lock_destroy from inside a spinlock
protected region (or, in general, from atomic context)
leads to a 'scheduling while atomic bug' because the
internal wakeup source deletion logic calls
synchronize_rcu, which can sleep. Moreover,
since the interal lists are already protected with
RCUs and spinlocks, putting the wake_lock_destroy
call in a spinlock is redundant.
