[FFmpeg-cvslog] lavf/tls_mbedtls: handle session ticket error code as no-op

[sfan5]

ffmpeg | branch: master | sfan5 <sfan5 at live.de> | Mon May 13 20:29:10 2024 +0200| [0455a62d8428ad0a21d2477ffd2d6440c0fdbd44] | committer: Anton Khirnov

lavf/tls_mbedtls: handle session ticket error code as no-op

When TLSv1.3 and session tickets are enabled mbedtls_ssl_read()
will return an error code to inform about a received session ticket.
This can simply be handled like EAGAIN instead of errornously
aborting the connection.
