[PATCH 1/9] s390: minor s390 network driver fixes

From: Frank Pavlic <fpavlic@de.ibm.com>
 - iucv driver:
          use do { } while (0) constructs 
   instead of empty defines to avoid compile bugs.
        - ctc driver:
          missing lock initialization added
        - lcs driver:
          BUG_ON usage was removed accidently 
   with the last lcs patch.
          Put them back in place.
