We know "ret" is zero so we don't need to test for it.  It upsets the
static checkers when we test stuff but we know the answer.

drivers/media/usb/as102/as102_usb_drv.c:164 as102_send_ep1() warn: we tested 'ret' before and it was 'false'
drivers/media/usb/as102/as102_usb_drv.c:189 as102_read_ep2() warn: we tested 'ret' before and it was 'false'

Also, we don't need to initialize "ret".
