can: peak_usb: pcan_usb_handle_bus_evt(): fix reading rxerr/txerr values

Browse source

This patch fixes an incorrect way of reading error counters in messages
received for this purpose from the PCAN-USB interface. These messages
inform about the increase or decrease of the error counters, whose values
are placed in bytes 1 and 2 of the message data (not 0 and 1).

Fixes: ea8b33bde7 ("can: pcan_usb: add support of rxerr/txerr counters")
