[PATCH] usb: gadget: dummy: fix infinite loop because of missing loop decrement

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The while loop never terminates because the loop counter i is never
decremented. Fix this by decrementing i.

Detected by CoverityScan, CID#751073 ("Infinite Loop")
