Subject: [PATCH] mount: improve error message when statd cannot be started.

If you try to mount and NFSv3 filesystem, and statd is not running
and cannot be started (maybe rpcbind isn't running either), the
error message is:

mount.nfs: rpc.statd is not running but is required for remote locking.
  mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
  mount.nfs: an incorrect mount option was specified

That last line is incorrect and misleading: no incorret mount option was
specified.

This line comes from mount_error() in error.c.  In this case that
function doesn't really need to provide any more information.

So introduce a concention that EALREADY means an error message has
already been printed, and use it to suppress that message.
