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signature, verify that a matching key has not been revoked and has not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.
