Szymon Janc a9ea3ed9b7 Bluetooth: Fix legacy pairing with some devices
Some devices e.g. some Android based phones don't do SDP search before
pairing and cancel legacy pairing when ACL is disconnected.

PIN Code Request event which changes ACL timeout to HCI_PAIRING_TIMEOUT
is only received after remote user entered PIN.

In that case no L2CAP is connected so default HCI_DISCONN_TIMEOUT
(2 seconds) is being used to timeout ACL connection. This results in
problems with legacy pairing as remote user has only few seconds to
enter PIN before ACL is disconnected.

Increase disconnect timeout for incomming connection to
HCI_PAIRING_TIMEOUT if SSP is disabled and no linkey exists.

To avoid keeping ACL alive for too long after SDP search set ACL
timeout back to HCI_DISCONN_TIMEOUT when L2CAP is connected.
