bonding: Fix 802.3ad no carrier on "no partner found" instance
Modify carrier state determination for 802.3ad mode to comply
with section 43.3.9 of IEEE 802.3, which requires that "Links that are
not successful candidates for aggregation (e.g., links that are attached
to other devices that cannot perform aggregation or links that have been
manually configured to be non-aggregatable) are enabled to operate as
individual IEEE 802.3 links."
Bug reported by Laurent Chavey <chavey@google.com>. This patch
is an updated version of his patch that changes the wording of
commentary and adds an update to the driver version.
