Quick hack fix for USB accessory audio support

Browse source 
tinyalsa fails to retrieve the correct value for the period count
from the f_audio_source driver and tries to use zero instead.
This wasn't a problem before because the usb audio HAL used hard coded values
that were compatible with the driver.
