KVM: arm64: Drop sort_memblock_regions()

Drop sort_memblock_regions() and avoid sorting the copied memory
regions to be ascending order on their base addresses, because the
source memory regions should have been sorted correctly when they
are added by memblock_add() or its variants.

This is generally reverting commit a14307f5 ("KVM: arm64: Sort
the hypervisor memblocks"). No functional changes intended.
