mmaldec: correct package buffering accounting

Browse Source 
The assert in ffmmal_stop_decoder() could trigger sometimes. The
packets_buffered counter was indeed not correctly maintained, and
packets were not subtracted from it if they were still in the waiting
queue.

For some reason, this happened especially with VC-1.
