[PATCH] keys: discard the contents of a key on revocation
Cause the keys linked to a keyring to be unlinked from it when revoked and it causes the data attached to a user-defined key to be discarded when revoked. This frees up most of the quota a key occupied at that point, rather than waiting for the key to actually be destroyed.
