Gerd Hoffmann 05a40b172e usb: limit combined packets to 1 MiB (CVE-2021-3527) 
usb-host and usb-redirect try to batch bulk transfers by combining many
small usb packets into a single, large transfer request, to reduce the
overhead and improve performance.

This patch adds a size limit of 1 MiB for those combined packets to
restrict the host resources the guest can bind that way.
