Bluetooth: Allow mgmt_device_found events for kernel-side scanning

Browse source 
When the kernel is doing LE scanning because of one or more devices
added with action 0x00 through the Add Device command we do want to let
mgmt_device_found() to proceed with sending an event. This kind of
devices are tracked with hdev->pend_le_reports, so check this value
before bailing out from the function.
