Modified Files:
        src/sys/arch/hp300/dev: rd.c

Log Message:
Fix "rd(4) at punits not configured on HPDisk are misprobed" problem.

- check not only stat value returned by C_QSTAT command against
  each punit but also desc.d_name returned by C_DESC command
  because it looks HPDisk responds to commands against punits supported
  but not-configured punits at 1-3
- prepare rdreset_unit() function to manage reset punit ops during
  probe without valid softc

The stragety is taken from OpenBSD with several modification.
Tested on 425t with real 9122D and HPDisk emulating two 7937H drives.

Should be pulled up to netbsd-9.
