Subject: [PATCH 1/1] can: usb: esd_usb2: Fix the interchange of the CAN RX and TX error counters.

This patch fixes the interchanged fetch of the CAN RX and TX error counters
from the ESD_EV_CAN_ERROR_EXT message. The RX error counter is really in
struct rx_msg::data[2] and the TX error counter is in struct rx_msg::data[3].
