Eric Dumazet 80bd490ac0 sock_map: Add a cond_resched() in sock_hash_free()
[ Upstream commit b1339be951ad31947ae19bc25cb08769bf255100 ]

Several syzbot soft lockup reports all have in common sock_hash_free()

If a map with a large number of buckets is destroyed, we need to yield
the cpu when needed.

Fixes: 75e68e5bf2 ("bpf, sockhash: Synchronize delete from bucket list on map free")
