avcodec/utvideoenc: Don't advertise unsupported option

Also return an better error code if it is set numerically.
(This option was added in 2862b63783b5556f7f3fb2d097629bc6879f833a
when an AVCodecContext generic option was moved to
a codec private one without realizing that not every
generic one is valid for every encoder.)
