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. 439

#
|
|
# Regression test for commit:
|
|
# 9c92ee2 ("xfs: validate sb_logsunit is a multiple of the fs blocksize")
|
|
#
|
|
# If log stripe unit isn't a multiple of the fs blocksize and mounting,
|
|
# the invalid sb_logsunit leads to crash as soon as we try to write to
|
|
# the log.
