ALSA: fireface: pick up time stamp for request subaction of asynchronous transaction
The time stamp of isochronous cycle at which asynchronous transaction is
sent is perhaps useful somehow. A commit b2405aa948b9 ("firewire: add
kernel API to access packet structure in request structure for AR context")
adds kernel API to retrieve the time stamp in inner structure of request
subaction.
This commit changes local framework to handle message delivered by the
asynchronous transaction so that time stamp is picked up by the kernel API.
