[PATCH] can: Add a helper function to get CAN bus state

[Benedikt Spranger]

For an application sending CAN frames the CAN bus state is crucial to know.
The CAN bus changes from "error active" (CAN frames can be send) to
"error passive" (CAN frames can *not* be send, but received) upon error count.
Add a helper function to get the CAN bus state.
