USB: serial: ch341: fix type promotion bug in ch341_control_in()
commit e33eab9ded328ccc14308afa51b5be7cbe78d30b upstream.
The "r" variable is an int and "bufsize" is an unsigned int so the
comparison is type promoted to unsigned. If usb_control_msg() returns a
negative that is treated as a high positive value and the error handling
doesn't work.
