[Qemu-devel] [PATCH] change auto filter output format of "info usbhost" (v1)

This patch changes the output format of the monitor command "info
usbhost" for usb auto filters in usb_host_info().

The VID and PID are now printed as 4 digit hexadecimal numbers with
leading zeros (which is much more usual compared to the current output
format which does not print leading zeros).
