Using %ps in a printk format will sometimes fail silently and
print the empty string if the address passed in does not match a
symbol that kallsyms knows about. But using %pS will fall back to
printing the full address if kallsyms can't find the symbol. Make
%ps act the same as %pS by falling back to printing the address.

While we're here also make %ps print the module that a symbol
comes from so that it matches what %pS already does. Take this
simple function for example (in a module):

	static void test_printk(void)
	{
		int test;
		pr_info("with pS: %pS\n", &test);
		pr_info("with ps: %ps\n", &test);
	}
