DEF_TIMEOUT is specified in seconds. The io_hdr timeout is specified in
milliseconds, so we need to convert it. Multipath should be waiting
longer than 30 milliseconds here. If there are concerns that 30 seconds
may be too long, we could always make this configurable, using
conf->checker_timeout if set.
