    Adjust a couple of error cases in camdd(8).
  
    usr.sbin/camdd/camdd.c:
    	In camdd_probe_file(), fix an error case after fstat where
    	we were bailing out and leaving two lines of cleanup code
    	unexecuted.  Instead, just goto bailout_error.
  
    	In camdd_probe_pass(), fail if the sector size is 0.
