riscv: Fix huge_ptep_set_wrprotect when PTE is a NAPOT
We need to avoid inconsistencies across the PTEs that form a NAPOT
region, so when we write protect such a region, we should clear and flush
all the PTEs to make sure that any of those PTEs is not cached which would
result in such inconsistencies (arm64 does the same).
