Gustavo Padovan dc2a0e20fb Bluetooth: Add missing lock nesting notation 
This patch fixes the following report, it happens when accepting rfcomm
connections:

[  228.165378] =============================================
[  228.165378] [ INFO: possible recursive locking detected ]
[  228.165378] 3.7.0-rc1-00536-gc1d5dc4 #120 Tainted: G        W
[  228.165378] ---------------------------------------------
[  228.165378] bluetoothd/1341 is trying to acquire lock:
[  228.165378]  (sk_lock-AF_BLUETOOTH-BTPROTO_RFCOMM){+.+...}, at:
[<ffffffffa0000aa0>] bt_accept_dequeue+0xa0/0x180 [bluetooth]
[  228.165378]
[  228.165378] but task is already holding lock:

[  228.165378]
[  228.165378] other info that might help us debug this:
[  228.165378]  Possible unsafe locking scenario:

[  228.165378]  *** DEADLOCK ***
[  228.165378]
[  228.165378]  May be due to missing lock nesting notation
