Subject: [PATCH 2/2] s3:rpc_client: Fix memory leak opening local named pipe
If no local server name was passed to rpc_pipe_open_local_np() then
get_myname() was called with NULL talloc context instead of the
current stackframe.
This was causing an increase of memory usage on busy servers with long-living
rpcd_* workers.
