qcow2: fix flushing after dirty bitmap metadata writes
update_header_sync itself does not need to flush the caches to disk.
The only paths that allocate clusters are:
- bitmap_list_store with in_place=false, called by update_ext_header_and_dir
- store_bitmap_data, called by store_bitmap
- store_bitmap, called by qcow2_store_persistent_dirty_bitmaps and
followed by update_ext_header_and_dir
So in the end the central place where we need to flush the caches
is update_ext_header_and_dir.
