Pull up following revision(s) (requested by jmcneill in ticket #970):

        external/cddl/osnet/dist/uts/common/fs/zfs/vdev_disk.c: revision 1.17
        external/cddl/osnet/dist/uts/common/fs/zfs/vdev_disk.c: revision 1.18

If calling d_minphys on the parent disk device, make sure we use the
parent disk device's dev_t. Fixes zfs on wedges on ld(4).
XXX pullup-9

Don't assume everything is a wedge and has a parent device. On non-wedges
this crashes.

Instead, just talk to the referenced device and rely on the dk driver
to pass requests correctly.
