[Reimar Döffinger]

ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Wed Jul 26 21:13:44 2023 +0200| [dcff15692dff4c55827d640f1d5d07eb255a5a6a] | committer: Reimar Döffinger

hevcdsp_idct_neon.S: Avoid unnecessary mov.

ret can be given an argument instead.
This is also consistent with how other assembler code
in FFmpeg does it.
