docs: T3871: describe how interface names are assigned
Names are no longer derived from the hw-id node. They are bound to the slot
the hardware occupies and recorded in a mapping file, so document what
decides a name, what happens when a card is replaced or added, and how to
rename an interface.
The troubleshooting page said to pin a MAC with hw-id when interfaces were
renamed after a VM migration or a clone. That node no longer exists and the
situation it describes no longer arises, so replace it with a pointer to the
new section and a note on where to look when an interface really is missing.
