rxrpc: Fix rack timer warning to report unexpected mode

rxrpc_rack_timer_expired() clears call->rack_timer_mode to OFF before
the switch. The default case warning therefore always prints OFF and
doesn't identify the unexpected timer mode.

Log the saved mode value instead so the warning reports the actual
unexpected rack timer mode.
