Yang Xu 2e356101e7 KEYS: reaching the keys quotas correctly ... Currently, when we add a new user key, the calltrace as below: add_key() key_create_or_update() key_alloc() __key_instantiate_and_link generic_key_instantiate key_payload_reserve ...... Since commit a08bf91ce2 ("KEYS: allow reaching the keys quotas exactly"), we can reach max bytes/keys in key_alloc, but we forget to remove this limit when we reserver space for payload in key_payload_reserve. So we can only reach max keys but not max bytes when having delta between plen and type->def_datalen. Remove this limit when instantiating the key, so we can keep consistent with key_alloc. Also, fix the similar problem in keyctl_chown_key().
