[PATCH 1/2] mount: ECONNREFUSED is a permanent error

I had assumed early on that mount.nfs should retry a refused connection.

Apparently this is not the case. Legacy mount.nfs4 fails immediately
if the NFS server refuses the connection. Legacy mount.nfs and
text-based mount.nfs both fail immediately if the rpcbind service is
refusing connections.

So, banish ECONNREFUSED returns from mount(2) to the domain of
permanent errors.
