Jia Lina 3d63da16fb migration: avoid segmentfault when take a snapshot of a VM which being migrated ... During an active background migration, snapshot will trigger a segmentfault. As snapshot clears the "current_migration" struct and updates "to_dst_file" before it finds out that there is a migration task, Migration accesses the null pointer in "current_migration" struct and qemu crashes eventually.
