[PATCH v2] xfstests: Introduce test case 285 to check statfs(2) will not cause ASSERT(XFS_IS_QUOTA_RUNNING(mp)) failed.

[Jeff Liu <jeff.liu@oracle.com>]

Hello,

Call statfs(2) against a project directory cause ASSERT(XFS_IS_QUOTA_RUNNING(mp)) at xfs_qm_dqget() failed pre-vanilla kernel-3.4
if the "pquota" or "prjquota" mount option was not enabled on the underlying partition.  This test case can help checking it.
