can: f81604: f81604_handle_can_bus_errors(): fix {rx,tx}_errors statistics
The f81604_handle_can_bus_errors() function only incremented the receive error counter and never the transmit error counter, even if the ECC_DIR flag reported that an error had occurred during transmission. Increment the receive/transmit error counter based on the value of the ECC_DIR flag.
