[PATCH] xfstests: 311: fsck the dmflakey device instead of the real device

[Josef Bacik <jbacik@xxxxxxxxxxxx>]

Dave pointed out that xfs was having issues with 311 because of caching issues.
He suggested that I fsck the dm-flakey device to make sure we don't have this
problem.  This is the easiest way I could think to accomplish this, please let
me know if this is a bad idea.  Thanks,
