[Qemu-devel] [PATCH v2] migration: Fix seg with missing port

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

The command :
   migrate tcp:localhost:

   currently segs; fix it so it now says:

   error parsing address 'localhost:'

and the same for -incoming.

Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
