usb: gadgetfs: return number of bytes on ep0 read request A read from GadgetFS endpoint 0 during the data stage of a control request would always return 0 on success (as returned by wait_event_interruptible) despite having written data into the user buffer. This patch makes it correctly set the return value to the number of bytes read.
