[PATCH 04/15] mka: Loss of live peers should result in connect PENDING not AUTHENTICATED

From: Mike Siedzik <msiedzik at extremenetworks.com>

When the number of live peers becomes 0 the KaY is setting
'kay->authenticated' true and telling the CP to connect AUTHENTICATED.
Per IEEE802.1X-2010 Clause 12.2, MKA.authenticated means "the Key Sever
has proved mutual authentication but has determiend that Controlled Port
communication should proceed without the use of MACsec", which means
port traffic will be passed in the clear.
When the number of live peers becomes 0 the KaY must instead set
'kay->authenticated' false and tell the CP to connect PENDING.  Per
Clause 12.3 connect PENDING will "prevent connectivity by clearing the
controlledPortEnabled parameter."
