Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create()
bt_sock_alloc() allocates the sk object and attaches it to the provided
sock object. On error l2cap_sock_alloc() frees the sk object, but the
dangling pointer is still attached to the sock object, which may create
use-after-free in other code.
