Dave Young 68845cb2c8 bluetooth : use lockdep sub-classes for diffrent bluetooth protocol 
'rfcomm connect' will trigger lockdep warnings which is caused by
locking diffrent kinds of bluetooth sockets at the same time.

So using sub-classes per AF_BLUETOOTH sub-type for lockdep.

Thanks for the hints from dave jones.
