powerpc/pkeys: Fix build error with PPC_MEM_KEYS disabled
IS_ENABLED() instead of #ifdef still requires variable declaration.
In this specific case, default_uamor is declared in asm/pkeys.h which
is only included if PPC_MEM_KEYS is enabled.
arch/powerpc/mm/book3s64/hash_utils.c: In function ‘hash__early_init_mmu_secondary’:
arch/powerpc/mm/book3s64/hash_utils.c:1119:21: error: ‘default_uamor’ undeclared (first use in this function)
1119 | mtspr(SPRN_UAMOR, default_uamor);
