[PATCH 01/11] keys: Invalidate used request_key authentication keys [ver #2]

[David Howells]

Invalidate used request_key authentication keys rather than revoking them
so that they get cleaned up immediately rather than potentially hanging
around.  There doesn't seem any need to keep the revoked keys around.
