[PATCH] ovl: change error message to info for empty lowerdir

[Eric Curtin <ecurtin@redhat.com>]

In some deployments, an empty lowerdir is not considered an error.
The current implementation logs this scenario as an error during boot,
which can be misleading and cause unnecessary concern for users. This
commit changes the log level from pr_err to pr_info to reflect the
non-error nature of an empty lowerdir in these cases.
