Because ceph_init_fs_context() will never be invoced in case we get a
mount error, destroy_mount_options() won't be releasing fscrypt resources

an invocation to this function in the mount error path.

Hi Luis,
BTW, any reason the following code won't be triggered ?
deactivate_locked_super(sb);
--> fs->kill_sb(s);
--> ceph_kill_sb()
--> kill_anon_super()
--> generic_shutdown_super()

Thanks!
