x86/pmu: Fix printed messages for emulated instruction test

This test case uses MSR_IA32_PERFCTR0 to count branch instructions
and PERFCTR1 to count instruction events. The same correspondence
should be maintained at report(), specifically this should use
status bit 1 for instructions and bit 0 for branches.
