mfvideosrc: Don't error out when if we've found supported format

Browse source 
While retrieving supported formats by device, the last return might
not be S_OK in case that it's not supported one by us (e.g., H264, JPEG or so).
But if we've found at least one supported raw video format,
we can keep going on.
