bug report - bluetoothctl ble connection

Hi Bluez,

I found a pairing/connection bug in bluetoothctl.

* Steps to reproduce:

[bluetoothctl] scan on
[bluetoothctl] pair ble_device
[bluetoothctl] connect ble_device
[bluetoothctl] exit

Right after exiting from bluetoothctl, Disconnect happens like below.

< HCI Command: Disconnect (0x01|0x0006) plen 3                [hci0] 156.978499
        Handle: 128
        Reason: Remote User Terminated Connection (0x13)

HCI Event: Command Status (0x0f) plen 4                     [hci0] 156.995345

      Disconnect (0x01|0x0006) ncmd 1
        Status: Success (0x00)

HCI Event: Disconnect Complete (0x05) plen 4                [hci0] 157.005387

        Status: Success (0x00)
        Handle: 128
        Reason: Connection Terminated By Local Host (0x16)
@ Device Disconnected: 00:22:D0:8D:22:6D (1) reason 2

* My observation1:
This is not the case of the hcitool. It works.

* My observation2:
Right after receiving GATT services, bluez does some more work.
But the Value doesn't look like normal.

......

ACL Data RX: Handle 128 flags 0x02 dlen 22                  [hci0] 132.295271

* I attached full hci logs.

Thanks,
