MFC r230921:
Insert ordered command every 1/4 of the current command timeout, not 1/4
of the default one.

Without this change setting kern.cam.ada.default_timeout to 1 instead of 30
allowed me to trigger several false positive command timeouts under heavy
ZFS load on a SiI3132 siis(4) controller with 5 HDDs on a port multiplier.
