Let's set desc->NumAdapters to zero as well when failure occurs.
If MS docs are trustworthy here, we don't have to do this:
If D3DKMT_ENUMADAPTERS2 returns an error, NumAdapters is undefined.
From my observations, Windows does not touch this value when returning `STATUS_BUFFER_TOO_SMALL`, but it's not easy to provoke other errors so I don't know what would be in `NumAdapters` if e.g. the OS ran out of memory or enumeration failed for some other reason.
