In dry-run mode, physical disk writes are skipped by dev_write().
If fsck_chk_quota_files() attempts to rebuild quota files, subsequent
reads on newly allocated blocks will fetch stale, unwritten disk data,
triggering assertion failures or false corruptions.

Skip updating quota files when dry-run mode is enabled, and report
inconsistent quota files as informational messages without flagging
unrepairable filesystem corruptions.
