Bluetooth: L2CAP: Fix checking if LTK is present

This fix a typo where incorrect member of bt_keys was used for checking if LTK is present. This was resulting in bogus results depending on connection role and current identity used. This was affecting L2CAP/LE/CFC/BV-25-C qualification test case. Fixes: zephyrproject-rtos#42862 Signed-off-by: Szymon Janc <[email protected]>
