Jakub Sitnicki 7499859881 bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself
[ Upstream commit 5b4a79ba65a1ab479903fff2e604865d229b70a9 ]

sock_map proto callbacks should never call themselves by design. Protect
against bugs like [1] and break out of the recursive loop to avoid a stack
overflow in favor of a resource leak.
