However, it doesn't clear the in-memory list of UUIDs received from advertising data, so when a device is scanned, connected and disconnected, the internal state still reflects that the UUIDs from the advertising data have already been handled. device_add_eir_uuids() ignored the UUIDs from the advertising data because both dev->le_state.svc_resolved == true and dev->eir_uuids still contains the UUIDs from the previous scan session. This fixes the issue by resetting both le_state.svc_resolved and eir_uuids when the device is disconnected.
