Bluetooth: Fix hardcoding ATT CID in __l2cap_chan_add()

Since in the future more than the ATT CID may be permissible we should
not be hardcoding it for all LE connections in __l2cap_chan_add().
Instead, the source ATT CID should only be set if the destination is
also ATT, and in other cases we should just use the existing dynamic CID
allocation function.

Assigning scid based on dcid means that whenever __l2cap_chan_add() is
called that chan->dcid is properly initialized. l2cap_le_conn_ready()
wasn't initializing is properly so this is also taken care of in this
