The existing code assumes that, if a device supports advertising monitor offload, DEVICE_FOUND events can be ignored since the kernel will send ADV_MONITOR_DEVICE_FOUND events instead. Unfortunately, these new events were added in 5.18, but offload was added in 5.12. This patch adds a check on the MGMT API version so we can process the older DEVICE_FOUND events when the new events are not supported.
