Another frame decode error.

[tyan0]

Openh264 fails to decode mp4 file:
https://tyan0.yr32.net/openh264/decode_frame_error2.mp4
with error.

I am not sure this is the right thing, however, the following patch solves the issue.

Could maintainer please have a look?

This errror handling was added by the commit e90068c mearged from PR #2070.
What situation is this necessary? And does the above code change break this fix?
