[FFmpeg-cvslog] udp: Properly print error from getnameinfo

[Martin Storsjö]

ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Tue Jun 19 15:28:48 2012 +0300| [860b40f1f2f5ed2cda0f4a8f44a631ffd2f94482] | committer: Martin Storsjö

udp: Properly print error from getnameinfo

getnameinfo doesn't set errno on failure, it returns an error code,
which should be handled by gai_strerror instead of the normal
strerror.
