ffmpeg | branch: master | Lynne <dev at lynne.ee> | Sat Mar 29 22:44:11 2025 +0000| [79ff1f21c4bcd2b917973357138829d44c3836be] | committer: Lynne

vulkan_decode: only create sequence params in end_frame

We tried to create sequence params in both start_frame and end_frame.
This was redundant.

Just always create them in end_frame.
