ipsec: increment SPD policy counters for bypass and discard actions in ipsec4_input_node
ipsec_spd_policy_counters are incremented only for matched inbound PROTECT actions (:273 and :370). BYPASS + DISCARD actions also have SPD policy counters that should be incremented on match. This fix increments the counters for inbound BYPASS and DISCARD actions. Type: fix Signed-off-by: Zachary Leaf <zachary.leaf@arm.com> Change-Id: Iac3c6d344be25ba5326e1ed45115ca299dee5f49
