Johan Hedberg 4e200fcacc Bluetooth: Fix NULL pointer dereference in smp_conn_security 
commit 25ba265390 upstream.

The l2cap_conn->smp pointer may be NULL for various valid reasons where SMP has
failed to initialize properly. One such scenario is when crypto support is
missing, another when the adapter has been powered on through a legacy method.
The smp_conn_security() function should have the appropriate check for this
situation to avoid NULL pointer dereferences.
