can: isotp: isotp_rcv_cf(): enable RX timeout handling in listen-only mode
As reported by Thomas Wagner:
https://github.com/hartkopp/can-isotp/issues/34
the timeout handling for data frames is not enabled when the isotp socket is
used in listen-only mode (sockopt CAN_ISOTP_LISTEN_MODE). This mode is enabled
by the isotpsniffer application which therefore became inconsistend with the
strict rx timeout rules when running the isotp protocol in the operational
mode.
This patch fixes this inconsistency by moving the return condition for the
listen-only mode behind the timeout handling code.
