ragel.rl: Make search_err read "p" before stop
If we stop before reading the "p" false positive may be returned since "p" may be the start of new token. Thus case like `type: 3u8[4] str;` would fail to mark the real error since '3' is not read. Thus start marking from the last valid token that is ':'.
