Subject: [PATCH 2/2] staging: r8188eu: Make some clean-ups in usbctrl_vendorreq()

After replacing usb_control_msg() with the new usb_control_msg_recv() and
usb_control_msg_send() API of USB Core, remove camelcase from the pIo_buf
variable that is passed as argument to the new API and remove the initial
'p' (that probably stands for "pointer") from the same pIo_buf and from
the pintfhdl and pdata arguments of usbctrl_vendorreq().
