Description of problem:
Guest will get a bsod while hibernating after block resize data disk.

Version-Release number of selected component (if applicable):
virtio-win-prewhql-59

How reproducible:
1 times

Steps to Reproduce:
1.boot up guest with 
/usr/libexec/qemu-kvm -m 4G -smp 4 -cpu cpu64-rhel6,+x2apic,family=0xf -usb -device usb-tablet -netdev tap,sndbuf=0,id=hostnet0,script=/etc/qemu-ifup,downscript=no -device e1000,netdev=hostnet0,mac=00:1c:3f:21:46:31 -uuid cccc6a20-2351-4762-a654-b7990c16d720 -no-kvm-pit-reinjection -chardev socket,id=111a,path=/tmp/monitor-R2-blk-scsi,server,nowait -mon chardev=111a,mode=readline -vnc :1 -rtc base=localtime,clock=host,driftfix=slew -chardev socket,id=seabios_debug,path=/tmp/monitor-seabios,server,nowait -device isa-debugcon,iobase=0x402,chardev=seabios_debug -drive file=win7-64-run.qcow2,if=none,media=disk,format=qcow2,rerror=stop,werror=stop,cache=none,aio=native,id=scsi-disk0 -drive file=disk1.qcow2,if=none,media=disk,format=qcow2,rerror=stop,werror=stop,cache=none,aio=native,id=scsi-disk1 -drive file=disk3.raw,if=none,media=disk,format=raw,rerror=stop,werror=stop,cache=none,aio=native,id=scsi-disk3 -drive file=disk4.raw,if=none,media=disk,format=raw,rerror=stop,werror=stop,cache=none,aio=native,id=scsi-disk4 -device virtio-scsi-pci,id=bus1 -device scsi-hd,bus=bus1.0,drive=scsi-disk0,id=disk,serial=test,bootindex=1 -device scsi-hd,bus=bus1.0,drive=scsi-disk1,id=disk1,serial=test1 -device scsi-hd,bus=bus1.0,drive=scsi-disk3,id=disk3,serial=test3,scsi-id=2,lun=3 -device scsi-hd,bus=bus1.0,drive=scsi-disk4,id=disk4,serial=test4,scsi-id=1,lun=4 -global PIIX4_PM.disable_s3=0 -global PIIX4_PM.disable_s4=0 -M rhel6.4.0 -spice port=5931,disable-ticketing -vga qxl -qmp tcp:0:4444,server,nowait -monitor stdio -device virtio-scsi-pci,id=bus2 -device scsi-hd,bus=bus2.0,drive=scsi-disk2,id=disk2 -drive file=disk2.raw,if=none,media=disk,format=raw,rerror=stop,werror=stop,cache=none,aio=native,id=scsi-disk2,serial=test2
2.block_resize scsi-disk4 to 15G [original is about 2G]
  Login to guest and check/format the new added disk.
3.do Hibernate 
  
Actual results:
It took a long time to hibernate and the guest got BSOD finally.

Expected results:
The guest can hibernate

DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time (usually 10 minutes).
Arguments:
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: fffffa800407b060, Physical Device Object of the stack
Arg3: fffff80000b9c518, nt!TRIAGE_9F_POWER on Win7, otherwise the Functional Device Object of the stack
Arg4: fffffa80039f37d0, The blocked IRP
