[RFC] Bluetooth: Do not attempt to send dlci disconnect when in BT_CONFIG.

[Kiran Kumar Raparthy]

From: Nick Pelly <npelly@xxxxxxxxxx>

Do not attempt to send dlci disconnect when in BT_CONFIG.

This fixes a bug where shutdown() and close() on a rfcomm socket during ACL
connection would not cause HCI Create Connection Cancel.

This is one of the number of patches from the Android AOSP common.git tree,
which is used on almost all Android devices.  so I wanted to submit it for
review to see if it should go upstream.
