ovl: return EINVAL instead of EIO in case of mismatched user_ns

Browse source

The EIO was used to signal an internal error (commit 9efb069de4 ("ovl:
add warning on user_ns mismatch")), which is no longer the case.

Fixes: 63981fc786 ("ovl: don't warn when the mount is completed from another user namespace")
