devctl: Disable the boottime optimization of suppressing NOMATCH
The usb bus code (uhub) doens't present the same information to devctl
as it does to the NOMATCH events it generats. As such, devmatch fails to
find USB devices on boot when NOMATCH events are optimized out. Since
the savings of boot time is relatively trivial for all but the most
demanding boot environments, disable it by default until this issue is
fixed.
