This is a regression test case to verify whether the CP_TRIMMED_FLAG is
properly set after performing the following steps:
1. mount the f2fs filesystem
2. create a file, write data to it, then delete the file
3. unmount the filesystem
4. verify that the 'trimmed' flag is set in the checkpoint state
We should apply the commit ("f2fs: fix missing discard for active
segments") to resolve the issue where the 'trimmed' flag is missing.

v2:
- Skip this test case if discard is not supported.
- Renumber this test case from 012 to 014.
