Bluetooth: ATT: Handle Indications

Browse source 
This adds the callback necessary to parse Indication PDU generating
proper Confirm response:

> ACL Data RX: Handle 3585 flags 0x02 dlen 8
      ATT: Handle Value Indication (0x1d) len 3
        Handle: 0x0014
          Data: 00
< ACL Data TX: Handle 3585 flags 0x00 dlen 5
      ATT: Handle Value Confirmation (0x1e) len 0
