Yin Fengwei e8d00c2cec local_gpa2hpa: INVALID_GPA also means failure of address conversion ...

Either INVALID_GPA or NULL returned from local_gpa2hpa means the
page walk failure. But current code only take care of NULL and
leave INVALID_GPA not detected.

It could trigger ACRN crash in root mode when guest have a invalid
gva.

We add INVALID_GPA check as well.
