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

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].
