riscv: Fix unused variable warning when BUILTIN_DTB is set

commit ef69d2559fe9 ("riscv: Move early dtb mapping into the fixmap
region") wrongly moved the #ifndef CONFIG_BUILTIN_DTB surrounding the pa
variable definition in create_fdt_early_page_table(), so move it back to
its right place to quiet the following warning:

../arch/riscv/mm/init.c: In function ‘create_fdt_early_page_table’:
../arch/riscv/mm/init.c:925:12: warning: unused variable ‘pa’ [-Wunused-variable]
  925 |  uintptr_t pa = dtb_pa & ~(PMD_SIZE - 1);
