Cong Wang e00a5c331b udp: Fix a memory leak in udp_read_sock() 
sk_psock_verdict_recv() clones the skb and uses the clone
afterward, so udp_read_sock() should free the skb after using
it, regardless of error or not.

This fixes a real kmemleak.

Fixes: d7f571188e ("udp: Implement ->read_sock() for sockmap")
