can: usb: esd_usb2: esd_usb2_rx_event(): fix the interchange of the CAN RX and TX error counters

Browse Source 
commit 044012b52029204900af9e4230263418427f4ba4 upstream.

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].

Fixes: 96d8e90382dc ("can: Add driver for esd CAN-USB/2 device")
