kvm_physical_sync_dirty_bitmap() calculates the ramblock offset in an awkward way from the MemoryRegionSection that passed in from the caller. The truth is for each KVMSlot the ramblock offset never change for the lifecycle. Cache the ramblock offset for each KVMSlot into the structure when the KVMSlot is created. With that, we can further simplify kvm_physical_sync_dirty_bitmap() with a helper to sync KVMSlot dirty bitmap to the ramblock dirty bitmap of a specific KVMSlot.
