arm/arm64: KVM: Fix and refactor unmap_range
commit 4f853a714bf16338ff5261128e6c7ae2569e9505 upstream.
unmap_range() was utterly broken, to quote Marc, and broke in all sorts
of situations. It was also quite complicated to follow and didn't
follow the usual scheme of having a separate iterating function for each
level of page tables.
Address this by refactoring the code and introduce a pgd_clear()
function.
