Series can: esd_usb: Some more preparation for supporting esd CAN-USB/3 |

  Moved the supply for cf->data[3] (bit stream position of CAN error)
outside of the "switch (ecc & SJA1000_ECC_MASK){}"-statement, because
this position is independent of the error type.

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