Adjust error msg for ImageNUMATopologyAsymmetric
ImageNUMATopologyAsymmetric provided an error message which
is inconsistent to code logic check, this patch modify the
error message to make it consist to code.

Title:
Good error message is needed when ImageNUMATopologyAsymmetric is
raised
Status in OpenStack Compute (nova):
Fix Released
Bug description:
When the ImageNUMATopologyAsymmetric exception is raised by
https://github.com/openstack/nova/blob/master/nova/virt/hardware.py#L1265-L1268,
the nova CLI fails with the following error:
ERROR (BadRequest): Asymmetric NUMA topologies require explicit
assignment of CPUs and memory to nodes in image or flavor (HTTP 400)
(Request-ID: req-645017cd-d426-4e57-a2e9-587f1d5c84b7)
The above error message is not user-friendly at all in my opinion ;)
Instead, an error message like:
"(Number of vcpus of the flavor) modulus (numa_nodes) must be greater than
zero, or,
(Memory of the flavor) modulus (numa_nodes) must be greater than zero"
will be very useful to the user.
This error message will match the code in
https://github.com/openstack/nova/blob/master/nova/virt/hardware.py#L1265-L1268.
A better error message will help users set the right number of vcpus,
memory in the flavor and numa_nodes in order to boot a nova VM with
NUMA successfully.
