Minimal reproducer
When a descriptor set layout is created with
VK_DESCRIPTOR_BINDING_VARIABLE_DESCRIPTOR_COUNT_BIT_EXT, descriptorCount in
VkDescriptorSetLayoutBinding should be treated as an upper bound. The actual
descriptor count is provided in
VkDescriptorSetVariableDescriptorCountAllocateInfoEXT when
vkAllocateDescriptorSets() is called. radv uses the upper limit from
VkDescriptorSetLayoutBinding as descriptor count and fails to allocate
descriptor sets with VK_ERROR_OUT_OF_POOL_MEMORY.
The attached program reproduces the bug.</pre>
