[PATCH 009/110] xfs: create a static name for the dot entry too

From: Darrick J. Wong <djwong@kernel.org>

Source kernel commit: e99bfc9e687e208d4ba7e85167b8753e80cf4169

Create an xfs_name_dot object so that upcoming scrub code can compare
against that. Offline repair already has such an object, so we're
really just hoisting it to the kernel.
