Revert: "crypto: af_alg - Disallow bind/setkey/... after accept(2)"
This reverts commit 06b4194533ff92ed5888840e3a6beaf29a8fe5d4 which is
commit c840ac6af3f8713a71b4d2363419145760bd6044 upstream.
It's been widely reported that this patch breaks existing userspace
applications when backported to the stable kernel releases. As no fix
seems to be forthcoming, just revert it to let systems work again.
