pcwd.c: fix oops on unload

From Arkadiusz Miskiewicz <arekm@pld-linux.org>

  This patch is from Alan Cox and fixes problems when pcwd driver is loaded
  while there is no pcwd hardware installed.
  No idea why it was not feeded to you.
  Problem is described here
  http://www.ussg.iu.edu/hypermail/linux/kernel/0308.1/0178.html and tracked
  down in private conversation with Cox.
