The commit below disables tests requires scratch dev running on NFS

c041421 xfstests: stop special casing nfs and udf

Now re-enable them to get a larger test coverage on NFS.

Also do more updates to avoid unnecessary failures on NFS.

I tested against NFSv3 NFSv4.0 NFSv4.1 (both server and client are linux
running 3.18-rc1 kernel), the results look good.

Failures on NFSv3:
generic/035 generic/089 generic/258 generic/294

Failures on NFSv4.0:
generic/035 generic/169 generic/294

Failures on NFSv4.1:
I hit kernel BUG_ON when testing on NFSv4.1 in generic/285
SEEK_DATA/SEEK_HOLE test. I think there's already a patch to fix it.

Note that generic/294 does remount,ro on SCRATCH_DEV, but TEST_DEV is
affected too, so some tests after generic/294 fail because of EROFS.
Run the failed tests separately and they all passed.

I'm not sure if it's a bug, but I filed one, please see
https://bugzilla.redhat.com/show_bug.cgi?id=1158046

The third patch disables all atime related tests on NFS, and Christoph
starts a discussion about NFS atime handling issue in v1 thread. Before
there's a conclusion I keep the patch as it is, and we can update it
later when we decide to test atime on NFS again.

v2:
- introduce _scratch_cleanup_files helper to remove all files on
  $SCRATCH_MNT, for later CIFS use. (Christoph Hellwig)
- split _require_relatime change into another patch (Christoph Hellwig)

v1: http://www.spinics.net/lists/linux-nfs/msg47423.html

Thanks,
Eryu
