nfc: fix memory leak in llcp_sock_connect()
commit 7574fcdbdcb335763b6b322f6928dc0fd5730451 upstream.
In llcp_sock_connect(), use kmemdup to allocate memory for
"llcp_sock->service_name". The memory is not released in the sock_unlink
label of the subsequent failure branch.
As a result, memory leakage occurs.
