[PATCH 5/5] xfs: don't run tests that require v4 file systems when not supported

[Christoph Hellwig <hch@lst.de>]

Add a _require_xfs_nocrc helper that checks that we can mkfs and mount
a crc=0 file systems before running tests that rely on it to avoid failures
on kernels with CONFIG_XFS_SUPPORT_V4 disabled.
