usb: gadget: f_diag: Decrement counter if zero length packet queueing fails
If usb_ep_queue() fails on queueing zero-length packet, driver is not
decrementing dpkts_tolaptop_pending counter which may results into seeing
count mismatch. Hence decrement dpkts_tolaptop_pending if zero length
packet queueing fails.
