[PATCH 4.9 08/59] net/sched: cls_flower: Fix missing addr_type in classify

4.9-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 0df0f207aab4f42e5c96a807adf9a6845b69e984 ]

Since we now use a non zero mask on addr_type, we are matching on its
value (IPV4/IPV6). So before this fix, matching on enc_src_ip/enc_dst_ip
failed in SW/classify path since its value was zero.
This patch sets the proper value of addr_type for encapsulated packets.
