[Leo Izen]

ffmpeg | branch: master | Leo Izen <leo.izen at gmail.com> | Fri Jun 21 17:20:13 2024 -0400| [539d2e989d7ce3556a549d59ee9c5125ae7d7b6b] | committer: Leo Izen

avcodec/aacdec_lpd: remove unused local variables

int idx, and int first_tcx_flag are set but not used, so this commit
removes their declarations and assignments.
