Jack Lau 13c91c97d1 avcodec/libjxldec: goto SUCCESS when frame is completed
Fix #21260

The early code didn't reset the JxlDecoder. If the
caller re-send the same packet to JxlDecoder after
avcodec_flush_buffers() (free ctx->frame). It will
directly hit SUCCESS event (skip all EVENTs).

In this case, the ctx->frame already flushed by
avcodec_flush_buffers, so the received frame
will be invalid (has no private_ref) that causes
assertion in decode_receive_frame_internal().

MPV meet this issue because it seek the jxl image
(second read the same pkt) when it does crop
through config `C vf toggle crop=in_w:in_w/2.4`.

This patch make sure hit the entire SUCCESS event
(contains reset the JxlDecoder) when frame_complete
is true.
