RISC-V: Fix up a cherry-pick warning in setup_vm_final()

Browse Source 
This triggers a -Wdeclaration-after-statement as the code has changed a
bit since upstream.  It might be better to hoist the whole block up, but
this is a smaller change so I went with it.

arch/riscv/mm/init.c:755:16: warning: mixing declarations and code is a C99 extension [-Wdeclaration-after-statement]
             unsigned long idx = pgd_index(__fix_to_virt(FIX_FDT));
                           ^
