when migrate the vm with quick speed, i find vnc response slowly.
the bug can be reproduce by this command:
virsh migrate-setspeed 165cf436-312f-47e7-90f2-f8aa63f34893 900
virsh migrate --live 165cf436-312f-47e7-90f2-f8aa63f34893
--copy-storage-inc qemu+ssh://10.59.163.38/system
and --copy-storag
when migration with quick speed, mig_save_device_bulk invoke
bdrv_is_allocated too frequently, and cause vnc reponse slowly.
this patch limit the time used for bdrv_is_allocated.
