Bluetooth: hci_event: Fix sending MGMT_EV_DEVICE_FOUND for invalid address

Browse Source 
[ 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
a2ec905d1e ("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.
