module: fix lost error code from codetag_load_module()
If codetag_load_module() fails, err is not set to reflect the failure
and load_module() returns 0 after the module has been torn down.
Also, if the module is a livepatch, mod->klp_info allocated by
copy_module_elf() leaks on this error path. Free it via a new
livepatch_cleanup label.
