kvm-all: Sync dirty-bitmap from kvm before kvm destroy the corresponding dirty_bitmap
Sometimes, we destroy the dirty_bitmap in kvm_memory_slot before any sync action occur, this bit in dirty_bitmap will be missed, and which will lead the corresponding dirty pages to be missed in migration. This usually happens when do migration during VM's Start-up or Reboot.
