David Howells 5d6af6f9dd afs: Fix key refcounting in file locking code ...

[ Upstream commit 59d49076ae ]

Fix the refcounting of the authentication keys in the file locking code.
The vnode->lock_key member points to a key on which it expects to be
holding a ref, but it isn't always given an extra ref, however.
