skbuff: Fix not waking applications when errors are enqueued

commit 6e5d58fdc9bedd0255a8781b258f10bbdc63e975 upstream.

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).

[bwh: Backported to 3.2: sk_data_ready() operation takes a length parameter.
 Delete the local variable we used for that.]
