KVM: SEV: Read start/end indices of PSC requests exactly once per #VMGEXIT
Rework Page State Change (PSC) handling to read the guest-provided start
and end indices exactly once, at the beginning of the request. Re-reading
the indices is "fine", _if_ the guest is well-behaved. KVM _should_ be
safe against concurrent guest modification of the indices, but there is
zero reason to introduce unnecessary risk.
