KVM: SEV: Document that checking for SEV+ guests when reclaiming memory is "safe"

Document that the check for an SEV+ guest when reclaiming guest memory is
safe even though kvm->lock isn't held.  This will allow asserting that
kvm->lock is held in the SEV accessors, without triggering false positives
on the "safe" cases.

No functional change intended.
