[PATCH v2] xfs/187: fix new sb_features2 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.

New common function _require_old_xfs_format() will help to fix
this problem. Call it as:

  _require_old_xfs_format ATTR2 LAZYSBCOUNT

Then it'll help to clear all features2 bits, besides ATTR2 and
LAZYSBCOUNT which will be tested in case.

Hi,

V2 add a new common function _require_old_xfs_format(), which help to
to make sure no features2 xfs bits will be set.

But mostly we still want to test some features2 bits, so I make
this function won't deal with those features which are specified by
arguments.

For clear CRC feature, we can set MKFS_OPTIONS="$MKFS_OPTIONS -m crc=0"
simply. But if the user specify crc=1/0 in local.config file, the test
can't continue running. So I check if it has been set in the function.

Please tell me if you have better way to implement this function:)

By the way, did I miss some features2?

Thanks,
Zorro
