chenzefeng 41330a743f ia64:unwind: fix double free for mod->arch.init_unw_table
[ Upstream commit c5e5c48c16422521d363c33cfb0dcf58f88c119b ]

The function free_module in file kernel/module.c as follow:

void free_module(struct module *mod) {
	......
	module_arch_cleanup(mod);
	......
	module_arch_freeing_init(mod);
	......
}

Both module_arch_cleanup and module_arch_freeing_init function
would free the mod->arch.init_unw_table, which cause double free.

Here, set mod->arch.init_unw_table = NULL after remove the unwind
table to avoid double free.
