Under rare circumstances, after a reset, set_rx_mode might get called while the watchdog is running, which will cause a deadlock on the critical section lock. To correct this, add a counter and give up trying to get the lock after fifty tries. Log a message if this happens but don't take any other action. Because this happens after a reset, all of the Rx filters are still in place and the device won't lose connectivity. We can also get stuck during shutdown, if the PF has stopped communicating with us, or if a reset is occurring. If we can't get the lock after a reasonable amount of time, just error out. Something else bad is happening anyway, so adding this filter is the least of our concern right now.
