common: Check the file system consistency on SCRATCH_DEV

There are about 198 tests which requires scratch_dev, but does not check
the file system consistency afterwards. Xfstests infrastructure does not
do it automatically, so fix it by running _check_scratch_fs() after
each test that _require_scratch.

Also remove all the _check_scratch_fs() calls that are not actually needed
and will be covered by the check script.
