	src/sys/sys: device.h

Log Message:
The tricks done in device_foreach_child() still don't make it safe to use
by config_detach_children(), because the latter can work recursively
and remove any number of devices, so rewrite config_detach_children()
to restart list traversal after each call of config_detach(), and since
only one user of device_foreach_child() is left (in kern_drvctl.c),
and it is simpler to open-code the loop than to deal with callbacks,
just remove it.
