qcow2: move qcow2_store_persistent_dirty_bitmaps() before cache flushing
After calling qcow2_inactivate(), all qcow2 caches must be flushed, but this
may not happen, because the last call qcow2_store_persistent_dirty_bitmaps()
can lead to marking l2/refcont cache as dirty.
Let's move qcow2_store_persistent_dirty_bitmaps() before the caсhe flushing
to fix it.
