Pengcheng Yang 6105ed3598 bpf, sockmap: Fix missing BPF_F_INGRESS flag when using apply_bytes
[ Upstream commit a351d6087b ]

When redirecting, we use sk_msg_to_ingress() to get the BPF_F_INGRESS
flag from the msg->flags. If apply_bytes is used and it is larger than
the current data being processed, sk_psock_msg_verdict() will not be
called when sendmsg() is called again. At this time, the msg->flags is 0,
and we lost the BPF_F_INGRESS flag.

So we need to save the BPF_F_INGRESS flag in sk_psock and use it when
redirection.

Fixes: 8934ce2fd0 ("bpf: sockmap redirect ingress support")
