Previously, BPF TCP iterator was acquiring fast version of sock lock that disables the BH. This introduced a circular dependency with code paths that later acquire sockets hash table bucket lock. Replace the fast version of sock lock with slow that faciliates BPF programs executed from the iterator to destroy TCP listening sockets using the bpf_sock_destroy kfunc.
This batch should be moved before the bpf_sock_destroy patch.
