Revert "decklink: Fix debug logging warnings on Windows"

This reverts commit 845832263ba6b9e135b23e9a29c9d109cb2ee9c4.

The commit broke cross-mingw CI:
https://ci.gstreamer.net/job/GStreamer-master/8659/console

It seems that cross-mingw on Autotools and native-mingw on Meson
disagree about the size of HRESULT. Revert for now till I can
investigate the Meson side of things some more.
