Subject: [PATCH] mkb: Fix endless loop in _record
In case of a corrupt file it could happen that len get 0 in _record
and this results in an endless loop.
Created an exit condition for this case and fixed related
procedures too (they need to cope with the error-return-value
from _record).
Reason for change: https://github.com/OpenELEC/OpenELEC.tv/pull/4378
