[PATCH] xfs/187: fix new sb_features2 ftype stop case running

[Zorro Lang <zlang@redhat.com>]

This case is too old, at that time there's no "ftype" feature for
XFS. Due to this case need to clear features2 bits when mkfs.xfs,
so ftype bit stop case running for long time.

We care 6 features2 bits in this case:

  "ATTR2, LAZYSBCOUNT, PROJID32BIT, CRC, FTYPE, FINOBT"

ATTR2 and LAZYSBCOUNT bits will be tested in case. FINBOT will be
disabled if CRC=0. So this patch only check and disable PROJID32BIT,
CRC and FTYPE features when mkfs.xfs.

Hi,

I think we shouldn't skip this case if user doesn't specify suitable
MKFS_OPTIONS and MOUNT_OPTIONS. Because this case need complex options,
nearly no one will specify these all options for xfstests at same time.

Thanks,
Zorro
