can: hi311x: hi3110_can_ist(): fix potential use-after-free
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 error count information added to the CAN frame after netif_rx() is
a potential use after free, since there is no guarantee that the skb
is in the same state. It might be freed or reused.
Fix the issue by postponing the netif_rx() call in case of txerr and
rxerr reporting.
