ubifs: Fail commit if TNC is obviously inconsistent
A reference to LEB 0 or with length 0 in the TNC
is never correct and could be caused by a memory corruption.
Don't write such a bad index node to the MTD.
Instead fail the commit which will turn UBIFS into read-only mode.
This is less painful than having the bad reference on the MTD
from where UBFIS has no chance to recover.
