Bluetooth: Use address type info from user-space

Bluetooth: Use address type info from user-space

In order to establish a LE connection we need the address type
information. User-space already pass this information to kernel
through struct sockaddr_l2.

This patch adds the dst_type parameter to l2cap_chan_connect so we
are able to pass the address type info from user-space down to
hci_conn layer.
