Log message:
Introduce a disk_lookup() function which calls device_lookup(), before
verifying that the resulting device is present on the disklist. This
avoids a race whereby the disk driver can be accessed as soon as the
softc has been allocated, but before the disk has completed
initialisation and has called disk_attach() (up until this point
dk_label is still a null pointer).
Cut cd(4), sd(4) and wd(4) across to disk_lookup(). All callers of
disk_attach() need to be tested and cut over in due course.
