joerg cc4212cf2c Make open_disk() fail nicely upon encountering an ENOENT so to not
prematurely terminate the search for a usable disk.  ENOENT is quite
normal in particulare now with the advent of devfs.

While being here, also remove /dev/wd0 and /dev/od0 from the list of
disks to search since we don't have them anymore.
