Bug Description

L3 or DHCP agent may change port's status to BUILD although the port itself is not owned by the agent.
This causes various issues.

ML2: Change port status only when it's bound to the host

Currently, nothing prevents the port status to be changed to BUILD
state when get_device_details() is sent by a host that doesn't own
the port.
In some cases the port might stay in BUILD state.
This could happen during a live-migration, or for multi-hosted ports
such as HA ports.

This commit allows the port status modification only if the port
is bound to the host that is asking for it.
