nfc: llcp: Fix use-after-free in llcp_sock_release()

In the Linux kernel, the following vulnerability has been resolved:

nfc: llcp: Fix use-after-free in llcp_sock_release()

llcp_sock_release() unconditionally unlinks the socket from the local
sockets list.  However, if the socket is still in connecting state, it
is on the connecting list.

Fix this by checking the socket state and unlinking from the correct list.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
