[PATCH 5.10 01/15] xfs: don't assert fail on perag references on teardown

[Amir Goldstein <amir73il@gmail.com>]

From: Dave Chinner <dchinner@redhat.com>

commit 5b55cbc2d72632e874e50d2e36bce608e55aaaea upstream.

[backport for 5.10.y, prior to perag refactoring in v5.14]

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.
