CSIP coordinator was not finding its LTKs with Secure Connections, as
the fix in 9251e630efdd to make legacy pairing to work doesn't work with
SC.

Fix by keeping track of what kind of LTK we have, and not distinguishing
between central/peripheral key slots for SC, which kernel doesn't do and
AFAIK the role difference doesn't exist in SC.

LLM was used for bug triage and write initial version, but these are now
almost manually done.
