[PATCH] Fix _require_scratch test for extN, resierfs, gfs2, and btrfs

[Theodore Ts'o]

The extN, reiserfs, gfs2, and btrfs filesysytem types should use the
same check for a block device as XFS and UDF, and not the test for
NFS, which was checking for host:/foo/bar/baz when checking for a
scratch device.

Also, the NFS logic was also incorrect, in that it would allow a
zero-length SCRATCH_DEV to continue.
