eCryptfs: Validate global auth tok keys
commit 3891959846709a19f76628e33478cd85edb0e79f upstream. When searching through the global authentication tokens for a given key signature, verify that a matching key has not been revoked and has not expired. This allows the `keyctl revoke` command to be properly used on keys in use by eCryptfs.
