[PATCH] fix "no member named 'sect_attrs' of strcut module"

[Wu Zhangjin]

From: Wu Zhangjin <wuzhangjin@xxxxxxxxx>

The commit(1b364bf438cf337a3818aee77d68c0713f3e1fc4, "module: workaround
duplicate section names") introduced a condition to avoid null pointer
reference:

-       add_notes_attrs(mod, hdr->e_shnum, secstrings, sechdrs);
+       if (mod->sect_attrs)
+               add_notes_attrs(mod, hdr->e_shnum, secstrings, sechdrs);

but sect_attrs is only defined when CONFIG_KALLSYMS enabled, so this
patch is need to fix the following error:

error: 'struct module' has no member named 'sect_attrs'
