Edited

0X8000 is device manager module error base number defined in sdk_errors.h

#define DEVICE_MANAGER_ERR_BASE   (0x8000)

And anything on top of it is defined in nrf_error.h

#define NRF_ERROR_INVALID_ADDR                (NRF_ERROR_BASE_NUM + 16) ///< Bad Memory Address

This means that the handle you gave to the call is not identified by the device_manager. This is probably because the connection_id is not valid or BLE_GAP_EVT_SEC_PARAMS_REQUEST event has not been processed.

dm_service_context_set
{
    ...
    VERIFY_CONNECTION_INSTANCE(p_handle->connection_id);
    VERIFY_DEVICE_INSTANCE
}

I was stupid here, it is not invalid flags but invalid address error. I will edit my answer
