fsck.ubifs: Consolidate log
This is the 4/18 step of fsck. Consolidate log to ensure enough space
in log area. There could be following possible errors:
1. corrupted scanning data in log area: danger mode with rebuild_fs and
normal mode with 'yes' answer will turn to rebuild filesystem, other
modes will exit.
