D3D12: Fix invalid allocation size check.

GetResourceAllocationInfo() returns UINT_MAX64 when
the requested size is too large. This corrects the
validation to OOM when D3D considers the size
invalid.

Only validating for zero-size would cause a device
loss as certain D3D drivers may not always consider
zero-sized invalid and NextPowerOfTwo(UINT_MAX64)
would overflow the allocator.
