KEYS: remove unnecessary get/put of explicit dest_keyring
In request_key_and_link(), in the case where the dest_keyring was explicitly specified, there is no need to get another reference to dest_keyring before calling key_link(), then drop it afterwards. This is because by definition, we already have a reference to dest_keyring. This change is useful because we'll be making construct_get_dest_keyring() able to return an error code, and we don't want to have to handle that error here for no reason.
