Description of problem:
Boot guest with ehci and uhci storage attached simultaneous,qemu-kvm will be aborted with core dumped 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. boot guest
#/usr/libexec/qemu-kvm -M rhel6.2.0 -enable-kvm -m 2G -smp 2,cores=2,threads=1,sockets=1  -name RHEL6.1_32 -uuid 50eba0fa-c3bc-4634-9c87-e46fc4dafab9 -rtc base=utc,clock=host,driftfix=slew -boot c -drive file=/root/zhangjunyi/RHEL6.1_64-copy-2.qcow2,if=none,id=drive-ide-0-0,media=disk,format=qcow2,cache=none,werror=stop,index=0 -device virtio-blk-pci,drive=drive-ide-0-0,id=ide0-0-0,physical_block_size=4096,logical_block_size=512,bootindex=1 -netdev tap,id=hostnet1,vhost=on,sndbuf=0 -device virtio-net-pci,netdev=hostnet1,id=net1,mac=78:2B:CB:AF:11:11 -vnc :10 -monitor stdio -device virtio-balloon-pci,id=balloon0 
-device usb-ehci,id=ehci 
-device usb-storage,bus=ehci.0,drive=usbstick1 
-drive if=none,id=usbstick1,file=/root/zhangjunyi/usbdevice1.qcow2 
-device usb-storage,bus=usb.0,drive=usbstick2
-drive if=none,id=usbstick2,file=/root/zhangjunyi/usbdevice2.qcow2 

Actual results:
After step1
qemu-kvm: savevm.c:1258: vmstate_register: Assertion `!se->compat || se->instance_id == 0' failed.
Aborted (core dumped)

Expected results:
Works well
