Corrige posibles advertencias de desreferencia de puntero nulo en las funciones dc_dmub_srv_cmd_list_queue_execute() y dc_dmub_srv_is_hw_pwr_up(). En ambas funciones, se estaba desreferenciando la variable 'dc_dmub_srv' antes de verificar si era nula. Esto podría provocar una desreferencia del puntero nulo si 'dc_dmub_srv' es nulo. La solución es comprobar si 'dc_dmub_srv' es nulo antes de eliminar la referencia a él. Por lo tanto, se mueven las comprobaciones nulas de 'dc_dmub_srv' al comienzo de las funciones para garantizar que 'dc_dmub_srv' no sea nulo cuando se desreferencia.
