[FFmpeg-cvslog] avcodec/pthread_slice: Combine allocating and zeroing entries

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Thu Jun 30 20:31:35 2022 +0200| [b4ca3c7e4e4a098651f013b80d9d88cc1dc4d6b7] | committer: Andreas Rheinhardt

avcodec/pthread_slice: Combine allocating and zeroing entries

Actually, ff_slice_thread_allocz_entries() always already
allocates zeroed entries, so ff_reset_entries() was already
unnecessary. Make this more clear by renaming it to
ff_slice_thread_allocz_entries().
