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.
