UBIFS: ensure UBIFS switches to read-only on error
UBI transparently handles write errors by automatically copying and remapping the affected eraseblock. If UBI is unable to do that, for example its pool of eraseblocks reserved for bad block handling is empty, then the error is propagated to UBIFS. UBIFS must protect the media from falling into an inconsistent state by immediately switching to read-only mode. In the case of log updates, this was not being done.
