Current code matches subnqn and collapses all controllers to the same subnqn to a single subsystem structure. This is good for recognizing multiple controllers for the same subsystem. But with the well-known discovery subnqn, the subsystems aren't truly the same subsystem. As such, subsystem specific rules, such as no overlap of controller id, do not apply. With today's behavior, the check for overlap of controller id can fail, preventing the new discovery controller from being created. When searching for like subsystem nqn, exclude the discovery nqn from matching. This will result in each discovery controller being attached to a unique subsystem structure.
