Bluetooth: Fix l2cap conn failures for ssp devices
commit 18daf1644e634bae951a6e3d4d19d89170209762 upstream Commit 330605423c fixed l2cap conn establishment for non-ssp remote devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security is tested (which was always returning failure on any subsequent security checks). However, this broke l2cap conn establishment for ssp remote devices when an ACL link was already established at SDP-level security. This fix ensures that encryption must be pending whenever authentication is also pending.
