KVM/arm64 fixes for 5.16, take #1

- Fix the host S2 finalization by solely iterating over the memblocks instead of the whole IPA space

- Tighten the return value of kvm_vcpu_preferred_target() now that 32bit support is long gone

- Make sure the extraction of ESR_ELx.EC is limited to the architected bits

- Comment fixups
