[FFmpeg-cvslog] avcodec/hashtable: Zero-initialize hashtable

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Tue Jun  3 21:42:24 2025 +0200| [2fc310b2f25f9a803c9d5603e2efda384b3f1add] | committer: Andreas Rheinhardt

avcodec/hashtable: Zero-initialize hashtable

Otherwise ff_hashtable_freep() would try to free uninitialized
pointers upon allocation error (which happens in the corresponding
test tool).
