Masami Hiramatsu 4afc81cd1c perf symbols: Load map before using map->map_ip() 
In map_groups__find_symbol() map->map_ip is used without ensuring the
map is loaded. Then the address passed to map->map_ip isn't mapped at
the first time.

E.g. below code always fails to get a symbol at the first call;

	addr = /* Somewhere in the kernel text */
	symbol_conf.try_vmlinux_path = true;
	symbol__init();
	host_machine = machine__new_host();
	sym = machine__find_kernel_function(host_machine,
					 addr, NULL, NULL);
	/* Note that machine__find_kernel_function calls
	   map_groups__find_symbol */

This ensures it by calling map__load before using it in
map_groups__find_symbol().
