From: Chao Yu <yuchao0@huawei.com>

After fsync, filesystem should guarantee inode metadata including
project id being persisted, so even after sudden power-cut, during
mount, we should recover project_id fields correctly, in order to
not loss those meta info.

So adding this testcase to check whether generic filesystem can
guarantee that.

Better to add a new "LSATTR_PROG" entry as well in common/config and
_require_command "$LSATTR_PROG" lsattr

And use $CHATTR_PROG

and $LSATTR_PROG in the test.

Should be "project quota id"?
