vulkan/wsi/x11: Fix behavior of vkGetPhysicalDeviceSurfacePresentModesKHR

x11_surface_get_present_modes() is currently asserting that the number of elements in pPresentModeCount must be greater than or equal to the number of present modes available. This is buggy because pPresentModeCount elements are later copied from the...
