windows-deadlock-and-race-removal-20060427

This patch fixes:

* race conditions around cm_Lock() calls that were not protected
  by cm_SyncOp(LOCK) [asanka@secure-endpoints.com]

* deadlocks caused by obtaining smb_fid_t->mx after cm_scache_t->mx

* removes an extra Release smb_fid_t->mx that could result in
  releasing a mutex that is not currently held

* changes the log representation of several return codes and fids to
  be consistent with other output
