riscv: fix fs/proc/kcore.c compilation with sparsemem enabled
Failed to compile Fedora/RISCV kernel (5.4-rc3+) with sparsemem enabled:
fs/proc/kcore.c: In function 'read_kcore':
fs/proc/kcore.c:510:8: error: implicit declaration of function 'kern_addr_valid'; did you mean 'virt_addr_valid'? [-Werror=implicit-function-declaration]
510 | if (kern_addr_valid(start)) {
| ^~~~~~~~~~~~~~~
| virt_addr_valid
Looking at other architectures I don't see kern_addr_valid being guarded by
CONFIG_FLATMEM.
Fixes: d95f1a542c3d ("RISC-V: Implement sparsemem")
