can: rockchip_canfd: rkcanfd_handle_error_int_reg_ec(): fix decoding of error code...

Probably due to a copy/paste error rkcanfd_handle_error_int_reg_ec()
checks twice if the RKCANFD_REG_ERROR_CODE_TX_ACK_EOF bit is set in
reg_ec.

Keep the correct check for RKCANFD_REG_ERROR_CODE_TX_ACK_EOF and
remove the superfluous one.
