Yin Fengwei 68269a559f gpa2hva: add INVAVLID_HPA return value check ...

For return value of local_gpa2hpa, either INVALID_HPA or NULL
means the EPT walking failure. Current code only take care of
NULL return and leave INVALID_HPA as correct case.

In some cases (if guest page table is filled with invalid memory
address), it could crash ACRN from guest.

Add INVALID_HPA return check as well.
Also add @pre assumptions for some gpa2hpa usages.
