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.

Fixes: ba608c4f ("powerpc/fadump: fix race between pstore write and fadump crash trigger")
