[NET_SCHED]: cls_fw: fix NULL pointer dereference
When the first fw classifier is initialized, there is a small window
between the ->init() and ->change() calls, during which the classifier
is active but not entirely set up and tp->root is still NULL (->init()
does nothing).
When a packet is queued during this window a NULL pointer dereference
occurs in fw_classify() when trying to dereference head->mask;
