v4l2object: Don't set empty interlace-mode list
If for some reason we fail to probe formats (all try_fmt calls fail, for
example), this is not a critical error, but we end up with an empty list
of interlace modes. This causes all subsequent negotiation to fail.
This patch fixes interlace-mode setting to be skipped if we failed to
detect any.
