KEYS: trusted: Rollback init_trusted() consistently
commit 31de287 upstream. Do bind neither static calls nor trusted_key_exit() before a successful init, in order to maintain a consistent state. In addition, depart the init_trusted() in the case of a real error (i.e. getting back something else than -ENODEV).
