drm/panel: novatek-nt35950: Only unregister DSI1 if it exists

[ Upstream commit a50be876f4 ]

Commit 5dd45b6674 ("drm/panel: novatek-nt35950: Improve error handling")
introduced logic to unregister DSI1 on any sort of probe failure, as
that's not done automatically by kernel APIs.

It did not however account for cases where only one DSI host is used.
Fix that.
