[ Upstream commit eb73b5a9157221f405b4fe32751da84ee46b7a25 ]
This fixes sending MGMT_EV_DEVICE_FOUND for invalid address (00:00:00:00:00:00) which is a regression introduced by a2ec905d1e16 ("Bluetooth: fix kernel oops in store_pending_adv_report") since in the attempt to skip storing data for extended advertisement it actually made the code to skip the entire if statement supposed to send MGMT_EV_DEVICE_FOUND without attempting to use the last_addr_adv which is garanteed to be invalid for extended advertisement since we never store anything on it.
