Make getprotobynumber() calls in FilterCheck conditional on the log
levels by which they are used.  On a typical production setting (no
debug or filter logging) this will save an open/read/close system
call sequence per packet, approximately halving the system overhead
and reducing the overall overhead by 38%.
