5.15-stable review patch. If anyone has any objections, please let me know.

From: Chuck Lever chuck.lever@oracle.com
[ Upstream commit c7d7ec8f043e53ad16e30f5ebb8b9df415ec0f2b ]
Clean up: svc_shutdown_net() now does nothing but call svc_close_net(). Replace all external call sites.
svc_close_net() is renamed to be the inverse of svc_xprt_create().
