locking/qrwlock: Implement queue_write_unlock() using smp_store_release()

Since the following commit:

  536fa402221f ("compiler: Allow 1- and 2-byte smp_load_acquire() and smp_store_release()")

smp_store_release() supports byte accesses, so use that in writer unlock
and remove the conditional macro override.
