Cleaning after removing LOG_INFO_PURGE_NO_ROTATE.
Cleaning after removing LOG_INFO_PURGE_NO_ROTATE.


sql/sql_repl.cc:
  In my previous change I removed 'no_rotate' from MYSQL_LOG, so this made
  LOG_INFO_PURGE_NO_ROTATE useless (an error code which was never returned),
  so I remove it of the 'switch'.
