use actual request type as parameter
At the moment, usbctrl_vendorreq's requesttype parameter must be set to 1 for reading and 0 for writing. It's then converted to the actual bmRequestType for the USB control request. We can simplify the code and avoid this conversion if the caller passes the actual bmRequestType. This patch is an adaptation of commit 788fde031027 ("staging: rtl8188eu: use actual request type as parameter") for the new r8188eu driver.
