qemu: snapshot: restart CPUs when recover from interrupted snapshot job

Browse Source 
If we restart libvirtd while VM was doing external memory snapshot, VM's
state be updated to paused as a result of running a migration-to-file
operation, and then VM will be left as paused state. In this case we must
restart the VM's CPUs to resume it.
