actions set_field pack error

[DanielaSousa]

When the controller sends a Packet_Out with a SetField Action, the buffer_id and other fields would be set to zero, when packing the packet to be sent. On further debugging, I found that the problem is on function ofl_msg_pack_packet_out line: 227 ( https://github.com/ljerezchaves/ofsoftswitch13/blob/625f01384522579db8f1c361209319530d53774a/sources/oflib/ofl-messages-pack.c#L227 ) the pointer to buf is never updated while packing an action, which overwrites the packet_out fields.

Solution: just replace buf with ptr variable

ptr += ofl_actions_pack(msg->actions[i], (struct ofp_action_header *)ptr, ptr , exp);
