[ Upstream commit 118469f88180438ef43dee93d71f77c00e7b425d ]
Move the supply for cf->data[3] (bit stream position of CAN error), in
case of a bus- or protocol-error, outside of the "switch (ecc &
SJA1000_ECC_MASK){}"-statement, because this bit stream position is
independent of the error type.
Fixes: 96d8e90382dc ("can: Add driver for esd CAN-USB/2 device")
