** is_pseudo_bond=TRUE while loading bonds from NVS. There is no live
** connection at boot, so the side table cannot be consulted. The mark
** prevents the BTM_LE_KEY_PID handler from consolidating two pseudo
** bonds (which share the peer IRK / Identity) into one record and
** losing one LTK after reboot.
**
** Returns TRUE if a record was found and marked.
