[ovs-dev] [PATCH 04/16] ofp-actions: Store cookie in network byte order in struct ofpact_learn.

Most other code in Open vSwitch that works with flow cookies keeps them
in network byte order.  Using network byte order in struct ofpact_learn,
also, reduces the number of byte order conversions needed across the
source tree.
