[PATCH] module: potential uninitialized return in module_kallsyms_on_each_symbol()

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

Smatch complains that:

	kernel/module.c:4472 module_kallsyms_on_each_symbol()
        error: uninitialized symbol 'ret'.

This warning looks like it could be correct if the &modules list is
empty.

Fixes: 013c1667cf78 ("kallsyms: refactor {,module_}kallsyms_on_each_symbol")
