omxvideodec: prevent timeout when shutting down because of pending out buffers

Browse source 
The OMX transition state to Loaded won't be complete until all buffers
have been freed. There is no point waiting, and timeout, if we know that
output buffers haven't been freed yet.

The typical scenario is output buffers being still used downstream
and being freed later when released back to the pool.
