can: kvaser_usb_leaf: Set Warning state even without bus errors
kvaser_usb_leaf_rx_error_update_can_state() sets error state according to error counters when the hardware does not indicate a specific state directly. However, this is currently gated behind a check for M16C_STATE_BUS_ERROR which does not always seem to be set when error counters are increasing, and may not be set when error counters are decreasing. This causes the CAN_STATE_ERROR_WARNING state to not be set in some cases even when appropriate. Change the code to set error state from counters even without M16C_STATE_BUS_ERROR. The Error-Passive case seems superfluous as it is already set via M16C_STATE_BUS_PASSIVE flag above, but it is kept for now. Tested with 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778.
