tcp: fix races in tcp_abort()



commit 5ce4645c upstream.

tcp_abort() has the same issue than the one fixed in the prior patch
in tcp_write_err().

In order to get consistent results from tcp_poll(), we must call
sk_error_report() after tcp_done().

We can use tcp_done_with_error() to centralize this logic.

Fixes: c1e64e29 ("net: diag: Support destroying TCP sockets.")
