sock: set sk_err to ee_errno on dequeue from errq
When setting sk_err, set it to ee_errno, not ee_origin.
Commit f5f99309fa74 ("sock: do not set sk_err in
sock_dequeue_err_skb") disabled updating sk_err on errq dequeue,
which is correct for most error types (origins):
- sk->sk_err = err;
Commit 38b257938ac6 ("sock: reset sk_err when the error queue is
empty") reenabled the behavior for IMCP origins, which do require it:
+ if (icmp_next)
+ sk->sk_err = SKB_EXT_ERR(skb_next)->ee.ee_origin;
But read from ee_errno.
Fixes: 38b257938ac6 ("sock: reset sk_err when the error queue is empty")
