Eryu Guan 69eb6281a9 fstests: _fail test by default when _scratch_mount fails
Previously _scratch_mount didn't check the mount status and most
tests continue to run even if the mount failed (unless test checks
for the mount status explicitly). This would result in running tests
on the underlying filesystem (usually rootfs) and implicit test
failures, and such failures can be annoying and are usually hard to
debug.

Now _fail test by default if _scratch_mount failed and introduce
_try_scratch_mount for tests that need to check mount results
themselves.

# FS QA Test No. 434
#
# Ensure that we don't leak quota inodes when CoW recovery fails.
#
# Use xfs_fsr to inject bmap redo items in the log for a linked file and
# an unlinked file; enable quota so that we always mount with the quota
# inodes; and then corrupt the refcount btree to ensure that the CoW
# garbage collection (and therefore the mount) fail.
#
# On a subsequent mount attempt, we should be able to replay the bmap
# items for the linked and unlinked files without prematurely truncating
# the unlinked inode and without leaking the linked inode, and we should
# be able to release the quota inodes when we're aborting the mount. We
# also should not leak dquots.
