Bug 1516669 - Check init value of clearkey WMF decoder for failure. r=cpearce We weren't checking this value and it was causing compiler warnings. Instead this change means we check the value and log an error if init has failed. Differential Revision: https://phabricator.services.mozilla.com/D15519
