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: 776fe19953b0 ("ice: block default rule setting on LAG interface")
