====================
psp: correct notifications and device info around device assoc

We recently added the ability to associate a HW PSP device with
a software device like netkit or veth to be able to make PSP
usable from containers. This stretches the visibility of a PSP
device to multiple netns's.

Correct two minor issues:

[Patch 2] skip reporting the main ifindex in remote netns. I'm not sure
if we had some justification for this but looking back it's pretty
confusing. The ifindex is meaningless in another netns, better
not to have it.

[Patch 4] correct the change notification when net_device is removed.
The "leaving" notification had the removed netdev still listed among
the associated devices. This made the code simpler but really it makes
the notification impossible to interpret. Add the extra code to handle
this right, exclude the removed device, and send a del notification
when last device in a netns is chopped off.

Both of these were discovered by an LLM scan of the YAML spec,
the spec itself appears to not have major bugs.
