Subject: kmod: correct documentation of return status of request_module
If request_module() successfully runs modprobe, but modprobe exits with a
non-zero status, then the return value from request_module() will be that
(positive) error status. So the return from request_module can be:
negative errno
zero for success
positive exit code.
