Consider MGMT_STATUS_REJECTED as success for stop_passive_scanning().
MGMT_STATUS_REJECTED may be returned from kernel because the passive
scan timer had expired in kernel and passive scan was disabled just
around the time we called stop_passive_scanning().
This issue can be seen with BLE HoG devices trying to reconnect to BlueZ:
