Fix Desolace/Hinterlands Ghost Mushroom spawns

[Khaozx]

Their are 12 Ghost Mushrooms spawns in Desolace (outside of mara) that just never appear, same for the 4 spawns in the cave at the top of Jintha'alor in the Hinterlands. https://classicdb.ch/?object=142144

I can kinda support this suggestion. All of the custom content added in blizzlike zones are kinda annoying. Should stick to adding it in hyjal and other zones that aren't in use by blizzlike content
