SUNRPC: Don't leak sockets in xs_local_connect()
If there is still a closed socket associated with the transport, then we need to trigger an autoclose before we can set up a new connection. Reported-by: wanghai (M) <wanghai38@huawei.com> Fixes: f00432063db1 ("SUNRPC: Ensure we flush any closed sockets before xs_xprt_free()") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
