[Qemu-devel] [PATCH] vhost_dev_unassign_memory() don't assert if removing first entry in list.

[Jes.Sorensen@redhat.com]

From: Jes Sorensen <Jes.Sorensen@redhat.com>

If removing an entry from the list which is fully included in the
region and this is the first entry in the list. In this case 'to' can
go to -1, which is perfectly valid. Don't assert() on this case.
