Fix exception message in case when bulk creation fails.

In our client, for OpenStack client, we created a workaround for missing
bulk port create (at that time). Turns out, that running out of the
OpenStack resources, there could be SDKException thrown, which is fine,
although due to the mistake, message wasn't informative at all.
This patch is fixing this.
