[Issue]: CAN freezes/stops to send messages after restart from bus-off state.
Throws following log from kernel: "write: No buffer space available"
[Reason]: When message txfer starts, tx_object (which keeps track of active tx)
gets filled. If CAN goes to bus-off state, txfer remains incomplete for some
messages. In such case, tx_object bits will not get cleared. It will stop
adding more messages in controller RAM.
Along with tx_object, from network layer, there are socket echo buffers.
When CAN is initialized and up on network, netif_start_queue is pushed to start
transmission. When msg txfer starts, socket buffer gets filled and freed only
when txfer completes. During bus-off, since network queue remains ON, all the
queued msgs get filled in socket buffers and does not allow upcoming msgs.
Therefore we see "write: No buffer space available".
[Fix]: Clear tx_object when device goes to bus-off state and stop network queue.
Start network queue again during restart from bus-off.
