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.
