    Improve error message when migration status fail · 4041a4e3

     (“Make migration RPC non-blocking”) changed the API
    for reporting migration status, but has a small cosmetic bug: if the
    migration status if failure, but the RPC itself to get the status
    didn't fail, it shows the following error message:
      Could not migrate instance instance2: None
    since it always uses result.fail_msg, irrespective of which part of
    the if condition failed.
    This patch simply updates the msg if not already set, leading to:
      Could not migrate instance instance2: hypervisor returned failure
    Proper error display can be done once the migration status objects can
    return failure information as well, beside status.
