[vk] Remove improper check for image depth in texture cache. (#164)

Browse source 
When looking for existing images, ImageBase::TryFindBase checks the depth of the existing image to be greater than the layer of the base + depth of the candidate.
However the depth of images are not updated when cache were merged causing the lookup to fail.
This commit disables this faulty check to fix a critical memory leak that crashes the emulator in some games.
