InnoDB: Remove log debug code when UNIV_LOG_DEBUG is not defined

innobase/include/log0log.h:
  Remove debug variables unless #ifdef UNIV_LOG_DEBUG
innobase/include/log0log.ic:
  Remove log_check_log_recs() unless #ifdef UNIV_LOG_DEBUG
innobase/log/log0log.c:
  Remove log_debug_writes unless #ifdef UNIV_LOG_DEBUG

  Test log_debug_writes only #ifdef UNIV_LOG_DEBUG
