avformat/udp: avoid warning about always false comparison
socklen_t underlying type can be signed or unsigned depending on
platform. This is fine, just cast it to size_t before comparison.
Fixes: warning: result of comparison of unsigned expression < 0 is
always false [-Wtautological-unsigned-zero-compare]
