Rostislav Pehlivanov 5546294f63 lavfi/buffersrc: fix directly setting channel layout 
When setting the channel layout directly using AVBufferSrcParameters
the channel layout was correctly set however the init function still
expected the old string format to set the number of channels (when it
hadn't already been specified).
