BUG#55415 wait_for_update_bin_log enters a condition but does not leave

      
In sql/log.c, member function wait_for_update_bin_log, a condition is entered with
THD::enter_cond but is not exited. This might leave dangling references to the
mutex/condition in the per-thread information area.
      
To fix the problem, we call exit_cond to properly remove references to the mutex,
LOCK_log.
