rbd: reacquire lock should update lock owner client id
commit edd8ca8015800b354453b891d38960f3a474b7e4 upstream.
Otherwise, future operations on this RBD using exclusive-lock are
going to require the lock from a non-existent client id.
Fixes: 14bb211d324d ("rbd: support updating the lock cookie without releasing the lock")
