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.

Some of these changes are whitespace or renames.
They ought to be in a different patch.

I think you'll need 'reverse xmas tree' ordering as well.

You are right, thank you. We will revert it in v4 in all patches in this series :)
