Subject: [PATCH] xfs: don't assert fail on perag references on teardown
Git-commit: 5b55cbc2d72632e874e50d2e36bce608e55aaaea
Patch-mainline: v5.19-rc1
References: git-fixes

Not fatal, the assert is there to catch developer attention. I'm
seeing this occasionally during recoveryloop testing after a
shutdown, and I don't want this to stop an overnight recoveryloop
run as it is currently doing.

Convert the ASSERT to a XFS_IS_CORRUPT() check so it will dump a
corruption report into the log and cause a test failure that way,
but it won't stop the machine dead.
