[PATCH] USB: Usbmon setup DMA patch

Alan Stern sent me this patch. It goes on top of the patch the adds
mon_dmapeek:
 http://ftp.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/usb-usbmon-dma-areas.patch

Please be warned about ordering requirements or the build may fail.

Actually, mon_dmapeek is generic enough to support SETUP packets too.
