Don't limit the canbus_notify_tx() wakeup to cases where notify_local is set - perform the wakeup whenever the host_status field indicates the main task has work pending. This fixes a small race condition where the main task could block sending a usb echo frame, and the canbus_send() code gets called as the usb bandwidth becomes available but before a usb wakeup notification is sent. In that situation, the usb code may not issue a wake event and the echo frames may be delayed. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
