This patch fixes decrementing SCO connection reference right after
stablishing the SCO connection with defer setup enabled. The dump below
shows a disconnection command with handle 0, the connection is still in
BT_CONNECT2 state and there isn't a handle associated with it.
< HCI Command: Accept Synchronous Connection (0x01|0x0029) plen 21
bdaddr 78:47:1D:B3:72:6C
> HCI Event: Command Status (0x0f) plen 4
Accept Synchronous Connection (0x01|0x0029) status 0x00 ncmd 1
< HCI Command: Disconnect (0x01|0x0006) plen 3
handle 0 reason 0x13
Reason: Remote User Terminated Connection
> HCI Event: Command Status (0x0f) plen 4
Disconnect (0x01|0x0006) status 0x00 ncmd 1
> HCI Event: Synchronous Connect Complete (0x2c) plen 17
status 0x00 handle 46 bdaddr 78:47:1D:B3:72:6C
type eSCO
Air mode: CVSD
