tests: fix use of uninitialized variable cpu_info

Browse source 
On cpu-volume-test, cpu_info is initialized only on i386/amd64 systems,
and otherwise passed on to pa_cpu_init_orc() uninitialized.

If one was unlucky enough, they could end up with cpu_info.cpu_type ==
PA_CPU_X86 on a non-x86 system, and use and test the Orc codepath
without that being functional, and thus with the test failing.

This has been observed in the wild on the ppc64el Debian buildds. See
Debian bug #982740 for more context.

Define cpu_info here in the same way as in other tests.
