hwcontext_vulkan: do not chain structs of unsupported extensions in vkCreateDevice

Browse Source 
Fixes:

vkCreateDevice(): pCreateInfo->pNext<VkPhysicalDeviceOpticalFlowFeaturesNV> includes a
pointer to a VkPhysicalDeviceOpticalFlowFeaturesNV, but when creating VkDevice, the
parent extension (VK_NV_optical_flow) was not included in ppEnabledExtensionNames.
The Vulkan spec states: Each pNext member of any structure (including this one) in
the pNext chain must be either NULL or a pointer to a valid struct for extending
VkDeviceCreateInfo.
