Michael Ellerman ff446cd768 selftests/powerpc: Avoid GCC 12 uninitialised variable warning 
GCC 12 thinks that `actual` might be used uninitialised. It's not, the
use is guarded by `bad_mmcr2` which is only set to true at the same
point where `actual` is initialised.

  cycles_with_mmcr2_test.c: In function ‘cycles_with_mmcr2’:
  cycles_with_mmcr2_test.c:81:17: error: ‘actual’ may be used uninitialized [-Werror=maybe-uninitialized]
     81 |                 printf("Bad MMCR2 value seen is 0x%lx\n", actual);

Silence the warning by initialising `actual` to zero.
