ALSA: Use usb_set/get_intfdata 

Author: Julia Lawall <julia@diku.dk>

Use the USB functions usb_get_intfdata and usb_set_intfdata instead of
dev_get_drvdata and dev_set_drvdata, respectively.

The semantic patch that makes this change for the usb_get_intfdata case is
as follows: (http://www.emn.fr/x-info/coccinelle/)
