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.
