[PATCH] xfstests: fix flink test

[Josef Bacik <jbacik@xxxxxx>]

I don't have flink support in my xfsprogs, but it doesn't fail with "command not
found" or whatever, it fails because I don't have the -T option.  So fix
_require_xfs_io_command to check for an invalid option and not run.  This way I
get notrun instead of a failure.  Thanks,
