can: kvaser_usb_leaf: Fix improved state not being reported
[ Upstream commit 8d21f5927ae604881f98587fabf6753f88730968 ]
The tested 0bfd:0017 Kvaser Memorator Professional HS/HS FW 2.0.50 and
0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778 do not seem to send
any unsolicited events when error counters decrease or when the device
transitions from ERROR_PASSIVE to ERROR_ACTIVE (or WARNING).
This causes the interface to e.g. indefinitely stay in the ERROR_PASSIVE
state.
Fix that by asking for chip state (inc. counters) event every 0.5 secs
when error counters are non-zero.
Since there are non-error-counter devices, also always poll in
ERROR_PASSIVE even if the counters show zero.
Fixes: 080f40a6fa28 ("can: kvaser_usb: Add support for Kvaser CAN/USB devices")
