Use srcu console list iteration for console list traversal. It is acceptable because the consoles might come and go at any time. Strict synchronizing with console registration code would not bring any advantage over srcu. Document why the console_lock is still necessary. Note that this is a preparatory change for when console_lock no longer provides synchronization for the console list.
