Title:
NIC doesn't work with "pci=nomsi" in grub.conf
Status in QEMU:

Bug description:
qemu-kvm Commit:27f368604a3d27ca4ddac0f62a6928bb93cdacd5
NIC doesn't work with "pci=nomsi" in grub.conf. Neither static assignment
nor hot-plug assignment works.
And when using qemu-kvm's commit 08bb9f6b1a5d8f4f5dd5bafad2876067797cb8b4，
qemu doesn't have this problem.
Reproduce steps:
1.build and install qemu-kvm
2.plug off a NIC device from host (BDF of NIC: 13:00.0)
3.start a guest (grub.conf has a configuration "pci=nomsi") :
qemu-system-x86_64 -m 512 -smp 2 -device pci_assign,host=13:00.0 -hda
/share/ia32e-rhel5u5.img
4.[Guest] dhclient
The NIC assigned before cannot get an IP address. It doesn't work.
