msdkenc: break out of flush frames loop on error

Browse source 
In general, we should assume any unhandled error is
non-recoverable.

In the flush frames loop, some error states can cause us
to never increment the task and therefore we get stuck
in an infinite loop and generate GST_ELEMENT_ERROR
over and over again.  This eventually consumes all
system memory and triggers OOM.  Thus, assume the worst
and break out of the loop upon the first "unhandled" error.
