sctp: fix /proc/net/sctp/ memory leak
Commit 13d782f ("sctp: Make the proc files per network namespace.") changed the /proc/net/sctp/ struct file_operations opener functions to use single_open_net() and seq_open_net(). Avoid leaking memory by using single_release_net() and seq_release_net() as the release functions. Discovered with Trinity (the syscall fuzzer).
