Remove a double unlock in logsys.

In logsys there are a number of XYZ_unlocked() functions that are called
like this:

       pthread_mutex_lock (&logsys_config_mutex);

       XYZ_unlocked();

       pthread_mutex_unlock (&logsys_config_mutex);

The XYZ_unlocked() functions should not do any (un)locking.
But _logsys_config_subsys_get_unlocked() unlocks if it finds the subsys.
This means that there is 1 lock and 2 unlocks.
