net: can: kvaser_usb: fix reception on "USBcan Pro" and "USBcan R" type hardware.

commit a90f13b24fb40d02d11496cce6a10ae8d4b319b2 upstream.

Unlike Kvaser Leaf light devices, some other Kvaser devices (like USBcan
Pro, USBcan R) receive CAN messages in CMD_LOG_MESSAGE frames. This
patch adds support for it.
