Bluetooth: Allow 3D profile to use security mode 4 level 0
The PSM 0x0021 is dedicated to the 3D profile and has permission to use security mode 4 level 0 for L2CAP connectionless unicast data transfers. When establishing a L2CAP connectionless channel on PSM 0x0021, it will no longer force Secure Simple Pairing.
