module: correctly exit module_kallsyms_on_each_symbol when fn() != 0
Commit 013c1667cf78 ("kallsyms: refactor
{,module_}kallsyms_on_each_symbol") replaced the return inside the
nested loop with a break, changing the semantics of the function: the
break only exits the innermost loop, so the code continues iterating the
symbols of the next module instead of exiting.
Fixes: 013c1667cf78 ("kallsyms: refactor {,module_}kallsyms_on_each_symbol")
