Fix support for HW without output

Please test this patch. In order to test this, I may suggest these quick tests:

/* Should fail, not crash */
gst-launch-1.0 videotestsrc ! decklinksink device-number=0
gst-launch-1.0 videotestsrc ! decklinksink device-number=0

/* Should work ? */
gst-launch-1.0 decklinksrc device-number=0 ! videoconvert ! xvimagesink
gst-launch-1.0 decklinksrc device-number=1 ! videoconvert ! xvimagesink

/* Should fail, not crash */
gst-launch-1.0 decklinksrc device-number=2 ! videoconvert ! xvimagesink
