[PATCH v5 10/18] dyndbg: make ddebug_tables list LIFO for add/remove_module

[Jim Cromie]

loadable modules are the last in on this list, and are the only
modules that could be removed.  ddebug_remove_module() searches from
head, but ddebug_add_module() uses list_add_tail().  Change it to
list_add() for a micro-optimization.
