Tom Lendacky 1c24f24f6b x86/sev: Ensure SVSM reserved fields in a page validation entry are initialized to zero 
commit 3ee9cebd0a upstream.

In order to support future versions of the SVSM_CORE_PVALIDATE call, all
reserved fields within a PVALIDATE entry must be set to zero as an SVSM should
be ensuring all reserved fields are zero in order to support future usage of
reserved areas based on the protocol version.

Fixes: fcd042e864 ("x86/sev: Perform PVALIDATE using the SVSM when not at VMPL0")
