Takashi Sakamoto 03a954aef7 ALSA: oxfw: fix wrong reference count for stream functionality at error path of rawmidi interface 
In IEC 61883-6, several types of sampling data can be multiplexed into
payload of common isochronous packet (CIP). For typical audio and music
units, PCM samples and MIDI messages are multiplexed into one packet
streaming.

ALSA oxfw driver allows applications of rawmidi interface to start
packet streaming for transmission of MIDI messages. However at error
path, the reference count of stream functionality is not operated
correctly. This can brings a bug that packet streaming is not stopped
when all referrers release the count.

This commit fixes the bug.

Fixes: 4f380d0070 ("ALSA: oxfw: configure packet format in pcm.hw_params callback")
