USB: usb-gadget: unlock data->lock mutex on error path in ep_read()
ep_read() acquires data->lock mutex in get_ready_ep() and releases it on
all paths except for one: when usb_endpoint_xfer_isoc() failed. The
patch adds mutex_unlock(&data->lock) at that path.
Found by Linux Driver Verification project (linuxtesting.org).
