[PATCH 1/1] wined3d: Destroy the Vulkan command pool after cleaning up resources.

[Henri Verbeet]

From: Henri Verbeet

This fixes an issue exposed (but not caused) by commit
e553be7e776282fea77b8b60304298d9de90bd8b. Calling vkFreeCommandBuffers()
after the corresponding command pool was destroyed causes invalid memory
accesses. Thanks to Jacek for pointing this out.
