The Advanced Error Interrupt Message Number (bits 31:27 of the Root
Error Status Register) is updated when the number of msi messages assigned to a
device changes. Migration of windows 7 on q35 chipset failed because the check

to update these bits and we must restore this state across migration.

q35 isn't part of 1.1 so why do we want this patch there?
