ext4/044: Fix failure when mount options are incompatible with ext3

There are some mount options that are incompatible with ext3 filesystem
type. If they are used, this test fails because it tries to remount the
filesystem as ext3. The test makes sense even without remounting as ext3
so just make the test silently skip the remount.
