Bluetooth: Don't treat connection timeout as a failure
When we're doing background scanning and connection attempts it's possible we timeout trying to connect and go back to scanning again. The timeout triggers a HCI_LE_Create_Connection_Cancel which will trigger a Connection Complete with "Unknown Connection Identifier" error status. Since we go back to scanning this isn't really a failure and shouldn't be presented as such to user space through mgmt. The exception to this is if the connection attempt was due to an explicit request on an L2CAP socket (indicated by params->explicit_connect being true). Since the socket will get an error it's consistent to also notify the failure on mgmt in this case.
