net: usb: raw_ip: max_intfs to be non-writable

max_intfs is a varible which determines loop counts in driver
functions at runtime. Userspace could modify its default value at
module load time but it shouldn't be changed at runtime.

USB: convert drivers/net/* to use module_usb_driver()

This converts the drivers in drivers/net/* to use the
module_usb_driver() macro which makes the code smaller and a bit
simpler.

Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.
