icnss2: Use event_data before posting event

In icnss_pdr_notifier_cb() API, event_data gets free while
processing PD_SERVICE_DOWN event. In the same function
event_data->crashed is checking after posting PD_SERVICE_DOWN
event which may cause using event_data even after free.

This commit updates checking for event_data->crashed before
posting PD_SERVICE_DOWN event.
