io_ops abstraction is useless in this driver, since there is only one ops registration. Without io_ops we can get rid of indirect calls mess and shorten the calls chain. Shorten the calls chain of rtw_read8/16/32() down to the actual reads. For this purpose unify the three usb_read8/16/32 into the new usb_read(); make the latter parameterizable with 'size'; embed most of the code of usbctrl_vendorreq() into usb_read() and use in it the new usb_control_msg_recv() API of USB Core. Shorten the calls chain of rtw_write8/16/32() down to the actual writes. For this purpose unify the four usb_write8/16/32/N() into the new usb_write(); make the latter parameterizable with 'size'; embed most of the code of usbctrl_vendorreq() into usb_write() and use in it the new usb_control_msg_send() API of USB Core. The code with the modifications was thoroughly tested by Pavel Skripkin using a TP-Link TL-WN722N v2 / v3 [Realtek RTL8188EUS] Fabio M.
