Michael Ellerman 5f987caec5 powerpc/fadump: Fix build error with CONFIG_PRESERVE_FA_DUMP=y ...

skiroot_defconfig fails:

arch/powerpc/kernel/fadump.c:48:17: error: ‘cpus_in_fadump’ defined but not used
   48 | static atomic_t cpus_in_fadump;

Fix it by moving the definition into the #ifdef where it's used.
