Subject: [PATCH] fix: after screen-recorder finished, dock will coredump

When screen-recorder finish recording, will notify dock update item, and dock
will clean all item and readded back. But m_dragInfo->dockItem still point to
old item which has been cleaned.
So dock will coredump, while using this pointer to judge item can drag or not.

log: update m_dragInfo->dockItem pointer when dock itemCountChanged.
