ALSA: oxfw: fix to handle correct stream for PCM playback

Browse Source 
When userspace application calls ioctl(2) to configure hardware for PCM
playback substream, ALSA OXFW driver handles incoming AMDTP stream.
In this case, outgoing AMDTP stream should be handled.

This commit fixes the bug for v5.3-rc kernel.
