This prints the attribute information on ATT_REQ_RSP to make it easier
to identify to which handle the response is for:

> ACL Data RX: Handle 42 flags 0x02 dlen 9
      Channel: 65 len 5 sdu 3 [PSM 39 mode Enhanced Credit (0x81)] {chan 1}
      ATT: Read Response (0x0b) len 2
        Value: 0300
        Handle: 0x0030 Type: Source ASE (0x2bc5)
            ASE ID: 3
            State: Idle (0x00)
