[PATCH v10 03/16] staging: r8188eu: remove test in usbctrl_vendorreq()

["Fabio M. De Francesco" <fmdefrancesco@gmail.com>]

Remove unnecessary test for "!io_buf" in usbctrl_vendorreq(). This test
is not necessary because io_buf has been assigned with the address of
a region of dynamically allocated memory (dvobj->usb_alloc_vendor_req_buf)
by rtw_init_intf_priv() in os_dep/usb_intf.c.
