[PATCH 1/2] winevulkan: Adequate vkEnumerateInstanceLayerProperties to the Vulkan spec

[Victor Hermann Chiletto]

The section for vkEnumerateInstanceLayerProperties states [1]:

On success, this command returns
 * VK_SUCCESS
 * VK_INCOMPLETE

On failure, this command returns
 * VK_ERROR_OUT_OF_HOST_MEMORY
 * VK_ERROR_OUT_OF_DEVICE_MEMORY

Always setting the layer count to zero and returning VK_SUCCESS is
valid, as even if the function is given an array in pProperties, it's
filled with zero layers
