vhost: remove an incorrect assert
The 'to' can go negative when the first region gets removed (it gets incremented by to 0 immediately afterward), which makes the assertion fail. Nothing breaks if to < 0 here so just remove the assert. Tested-by: David Ahern <daahern@cisco.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
