From: Vladimir Sementsov-Ogievskiy <vsement...@virtuozzo.com>
Without initialization to zero dirty_bitmap field may be not zero
for a bitmap which should not be stored and
qcow2_store_persistent_dirty_bitmaps will erroneously call
store_bitmap for it which leads to SIGSEGV on bdrv_dirty_bitmap_name.
