skbuff: Fix not waking applications when errors are enqueued
[ Upstream commit6e5d58fdc9
] When errors are enqueued to the error queue via sock_queue_err_skb() function, it is possible that the waiting application is not notified. Calling 'sk->sk_data_ready()' would not notify applications that selected only POLLERR events in poll() (for example). Fixes:1da177e4c3
