Subject[067/129] svcrpc: destroy server sockets all at once
3.2-stable review patch.  If anyone has any objections, please let me know.

Lines: 75
From: "J. Bruce Fields" <bfields@redhat.com>

commit 2fefb8a09e7ed251ae8996e0c69066e74c5aa560 upstream.

There's no reason I can see that we need to call sv_shutdown between
closing the two lists of sockets.
