[XFS] Merge xfs_rmdir into xfs_remove

Browse Source 
xfs_remove and xfs_rmdir are almost the same with a little more work
performed in xfs_rmdir due to the . and .. entries. This patch merges
xfs_rmdir into xfs_remove and performs these actions conditionally.

Also clean up the error handling which was a nightmare in both versions
before.
