NFC: Use dynamic initialization for rwlocks
commit fe235b58d517d623bf6d40c77afca1b0ee6fc85d upstream.
If rwlock is dynamically allocated but statically initialized it is
missing proper lockdep annotation.
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
