overlay: correct fsck.overlay exit code
fsck.overlay should return correct exit code to show the file system
status after fsck, instead of return 0 means consistency and !0 means
inconsistency or something bad happened.
Fix the following three exit code after running fsck.overlay:
- Return FSCK_OK if the input file system is consistent,
- Return FSCK_NONDESTRUCT if the file system inconsistent errors
corrected,
- Return FSCK_UNCORRECTED if the file system still have inconsistent
errors.
This patch also add a helper function to run fsck.overlay and check
the return value is expected or not.
[amir] rename helper to _overlay_fsck_expect, split define of FSCK_*
to a seprate path.
