… not own it
Commit adds destruction of the persisted in PSA ITS key if mesh does not own it (zero bit in the bitmap of persisted keys).
This is not standard mesh behavior, but might happen if something happens between removing key data in mesh and in the crypto library (for example power off in bettwen).
Previously, mesh wasn't able to import key with gotten stuck key id. The current fix reproduces more robust behavior.
