[PATCH v2 04/12] can: hi311x: fix txerr and rxerr reporting

[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

The commit a22bd630cfff ("can: hi311x: do not report txerr and rxerr
during bus-off") removed the reporting of rxerr and txerr even in case
of correct operation (i. e. not bus-off). The CAN frame is unnecessarily
set since netif_rx() has already been called. The patch fixes the issue
by postponing the netif_rx() call in case of txerr and rxerr reporting.
