Vulkan: Fix descriptor pool init in presence of atomic counters The descriptor pool was initialized with the number of atomic counter buffers, but we always use 8 storage buffers for atomic counter buffer emulation regardless of how many atomic counter buffers there. This change fixes the descriptor pool initialization by requesting 8 storage buffer descriptors if there are any atomic counter buffers.
