userns and mnt_idmap leak in open_tree_attr(2)
[ Upstream commit 0748e553df0225754c316a92af3a77fdc057b358 ]
Once want_mount_setattr() has returned a positive, it does require
finish_mount_kattr() to release ->mnt_userns. Failing do_mount_setattr()
does not change that.
As the result, we can end up leaking userns and possibly mnt_idmap as
well.
