vkd3d: Remove old entries in GPU VA allocator.

Browse Source 
The "allocations" array is filled with unused entries when D3D12 buffers
are destroyed. The majority of entries might be unused after running for
a while. Remove the entry when VA is freed in order to prevent
accumulation of unused entries. This makes destroying D3D12 buffers more
expensive.
