Bluetooth: Fix potential NULL dereference
The bnep_get_device function may be triggered by an ioctl just after a connection has gone down. In such a case the respective L2CAP chan->conn pointer will get set to NULL (by l2cap_chan_del). This patch adds a missing NULL check for this case in the bnep_get_device() function.
