This function doesn't belong here. It is not introduced by this patch
and it is used only within qemu_process.c.

Yes, I will move this to [PATCH 4/7] qemu: open VFIO FDs from libvirt 
backend and place it under qemu_process.h. It must have been misplaced 
in the wrong patch during rebasing - thanks for catching this.
