Garbage collect struct monitor_ops::load_routine.

While touching monitor_load in a previous patch, I noticed this method
is no longer set to anything other than NULL in the tree, so we can
remove it.

Tested by building with --enable-targets=all.

	Garbage collect 'struct monitor_ops'::load_routine.

	* monitor.h (struct monitor_ops) <load_routine>: Remove field.
	* monitor.c (monitor_load): No longer call
	current_monitor->load_routine.
	* dbug-rom.c (init_dbug_cmds): Don't set 'load_routine'.
	* m32r-rom.c (init_m32r_cmds): Don't set 'load_routine'.
	* ppcbug-rom.c (init_ppc_cmds): Don't set 'load_routine'.
