Hao Ge c79cf15eb3 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.

Fixes: 044d2aee6c ("alloc_tag: handle module codetag load errors as module load failures")
