usb-bus: convert USBDeviceClass init to realize

Browse source 
Add "realize/unrealize" in USBDeviceClass, which has errp
as a parameter. So all the implementations now use
error_setg instead of error_report for reporting error.

Note: this patch still keep "init" in USBDeviceClass, and
call kclass->init in usb_device_realize(), avoid breaking
git bisect. After realize all usb devices, will be removed.
