Kailun Qin 09b7b2e1ea Populate binding levels when concurrent ops fail 
Concurrent calls to _bind_port_if_needed may lead to a missing RPC
notification which can cause a port stuck in a DOWN state. If the only
caller that succeeds in the concurrency does not specify that an RPC
notification is allowed then no RPC would be sent to the agent. The
other caller which needs to send an RPC notification will fail since the
resulting PortContext instance will not have any binding levels set.

The failure has negative effects on consumers of the L2Population
functionality because the L2Population mechanism driver will not be
triggered to publish that a port is UP on a given compute node. Manual
intervention is required in this case.

This patch proposes to handle this by populating the PortContext with
the current binding levels so that the caller can continue on and have
an RPC notification sent out.

Closes-Bug: #1755810
