Don't set administratively disabled ports as ACTIVE
There was a race condition during port update to disable it.
In case when neutron-server receives port update call to set
admin_state_down on port, it sends PORT_UPDATE notification
to agents.
Then both L2 and DHCP agents start doing their job with port.
L2 agent asks neutron-server about device details and during
processing this call server sets port's status to DOWN if
its admin_state_up = False.
Problem is that sometimes just after that, DHCP agent will send
to neutron server notification that provisioning for this port
is finished.
As there is no any other provisioning block in db (because it
is just port update) neutron-server is setting port's status
to ACTIVE.
This patch fixes this issue by allowing to transition to
ACTIVE only ports which are administratively enabled.
