Kirill A. Shutemov 99c5c4c60e x86/mm: Make x86_platform.guest.enc_status_change_*() return an error
TDX is going to have more than one reason to fail enc_status_change_prepare().

Change the callback to return errno instead of assuming -EIO. Change
enc_status_change_finish() too to keep the interface symmetric.
