Bluetooth: add annotations for l2cap_data locking context
Add context analysis annotations for hci_conn::l2cap_data locking.
Also add necessary lockdep_assert_held() and __must_hold annotations
to prove the access is safe.
The access in smp_conn_security() is supposed to be guarded by the
caller holding lock that blocks concurrent l2cap_conn_del() eg.
hdev->lock, conn->lock or chan->lock. Mark unsafe as can't be
automatically checked now.
