CVE-2015-7498 Avoid processing entities after encoding conversion failures

For https://bugzilla.gnome.org/show_bug.cgi?id=756527 and was also raised by Chromium team in the past When we hit a convwersion failure when switching encoding it is bestter to stop parsing there, this was treated as a fatal error but the parser was continuing to process to extract more errors, unfortunately that makes little sense as the data is obviously corrupt and can potentially lead to unexpected behaviour.
