[PATCH] xfs: don't treat unknown di_flags[2] as corruption in scrub

[Eric Sandeen <sandeen@redhat.com>]

xchk_inode_flags[2]() currently treats any di_flags[2] values that the
running kernel doesn't recognize as corruption, and calls
xchk_ino_set_corrupt() if they are set.  However, it's entirely possible
that these flags were set in some newer kernel and are quite valid,
but ignored in this kernel.

(Validators don't care one bit about unknown di_flags[2].)

Call xchk_ino_set_warning instead, because this may or may not actually
indicate a problem.
