[kvm-unit-tests PATCH v2 1/7] riscv: Fix virt_to_phys again

[Andrew Jones]

The last fix was a bit hasty since we didn't double check that
virt_to_phys() was the right place for the fix, rather than
virt_to_pte_phys(), and of course it was the latter... All
architectures add on the offset in virt_to_pte_phys() and then
simply wrap virt_to_pte_phys() with virt_to_phys(), if they
implement virt_to_phys() at all. RISCV shouldn't be different.

Fixes: e1dd4ea76894 ("riscv: Fix virt_to_phys")
Fixes: 23100d972705 ("riscv: Enable vmalloc")
