On a related issue, do we need an extra return code for the case that
the SVSM got a fault when trying to access VMPL1 memory? Request
processing can fault for various reasons when accessing addresses passed
in via requests, should this be reported a SVSM_ERR_INVALID_ADDRESS or
is another code needed?
