configured, but after all adapters have been configured. When multiple
adapters are present, only the last configured adapter could be matched
to the boot device slot. The adapter attach routines now check if that
adapter slot matches the boot device slot and saves the softc pointer
for that controller. Then when the disks are configured, dk_establish()
matches the appropriate controller. Also change the rz boot device test
to include a check for the adapter so that it works when booting from a
disk on adapters other than the first one.
