[FFmpeg-devel] [PR] avformat/whip: use ffurl_closep instead of ffurl_close for dtls_uc (PR #22272)

[Nariman-Sayed via ffmpeg-devel <ffmpeg-devel@ffmpeg.org>]

PR #22272 opened by Nariman-Sayed
URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/22272
Patch URL: https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/22272.patch

ffurl_closep sets the pointer to NULL after freeing,
preventing potential use-after-free if whip_deinit
is called more than once or in error paths.

The adjacent ffurl_closep(&whip->udp) call already
uses the correct function, this fixes the inconsistency.
