Dave Ertman 3ce58b01ad ice: add NULL check in eswitch lag check ...

The function ice_lag_is_switchdev_running() is being called from outside of
the LAG event handler code.  This results in the lag->upper_netdev being
NULL sometimes.  To avoid a NULL-pointer dereference, there needs to be a
check before it is dereferenced.

Fixes: 776fe19953 ("ice: block default rule setting on LAG interface")
