xfs: mark a data structure sick if there are cross-referencing errors

mainline inclusion
from mainline-v5.12-rc4
commit 9de4b514
category: bugfix
bugzilla: 187526,https://gitee.com/openeuler/kernel/issues/I4KIAO

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9de4b514494a3b49fa708186c0dc4611f1fe549c

--------------------------------

If scrub observes cross-referencing errors while scanning a data
structure, mark the data structure sick.  There's /something/
inconsistent, even if we can't really tell what it is.
