usb: gadget: f_rndis: convert to new function interface with backward compatibility

Converting rndis to the new function interface requires converting
the USB rndis' function code and its users.

This patch converts the f_rndis.c to the new function interface.

The file is now compiled into a separate usb_f_rndis.ko module.

The old function interface is provided by means of a preprocessor
conditional directives. After all users are converted, the old interface
can be removed.
