vfio: platform: ignore missing reset if disabled at module init

commit 7a209c0d7f904745854c84999e551268b58c88cc from
git@git.assembla.com:cavium/WindRiver.linux.git

If reset requirement was relaxed via module parameter, errors caused by
missing reset should not be propagated down to the vfio core.
Otherwise initialization will fail.
