[PATCHv2] af_llc: fix types on llc_ui_wait_for_conn

The timeout is a long, we return it truncated if it is huge. Basically
harmless as the only caller does a boolean check, but tidy it up anyway.

(64bit build tested this time. Thank you 0day)

If the only caller performs a boolean check then perhaps
it would be best if the function's return type was bool.

Applied, thanks Alan.

Please take into consideration Simon's idea to change the return type to
bool as a follow-up.

Thanks.
