MDEV-10644 One of parallel replication threads remains active
           after STOP SLAVE SQL_THREAD completes

Using mysql_mutex_trylock() instead of mysql_mutex_lock() for LOCK_active_mi in
function show_slave_received_heartbeats() and show_heartbeat_period().
If can't aquire LOCK_active_mi lock after 1 seconds, then give up and just show
SHOW_UNDEF.
This is a temporary fix. If want to solve related problems completely, should
change the LOCK_active_mi to mysql_rwlock_t.
