Mitch Williams 54e16f64f0 i40evf: don't wait forever
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.
