[PATCH] vfs: Rename __is_local_mountpoint to is_local_mountpoint

[Nikolay Borisov <nborisov@suse.com>]

Current is_local_mountpoint is a simple wrapper with added d_mountpoint
check. However, the same check is the first thing which
__is_local_mountpoint performs. So remove the wrapper and promote the
private helper to is_local_mountpoint. No semantics changes.
