7.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hao Ge <hao.ge@linux.dev>

commit c79cf15eb35a4c703bf18f8c33c47e80dd660f8e upstream.

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.

Fixes: 044d2aee6c57 ("alloc_tag: handle module codetag load errors as module load failures")
