[kvm-unit-tests GIT PULL 05/16] Fix the length in the stsi check for the VM name

From: Thomas Huth <thuth@redhat.com>

sizeof(somepointer) results in the size of the pointer, i.e. 8 on a
64-bit system, so the

memcmp(data->ext_names[0], vm_name_ext, sizeof(vm_name_ext))

only compared the first 8 characters of the VM name here. Switch
to a proper array to get the sizeof() right.
