KVM: TDX: Account all non-transient page allocations for per-TD structures

Browse source

Account all non-transient allocations associated with a single TD (or its
vCPUs), as KVM's ABI is that allocations that are active for the lifetime
of a VM are accounted.  Leave temporary allocations, i.e. allocations that
are freed within a single function/ioctl, unaccounted, to again align with
KVM's existing behavior, e.g. see commit dd103407ca ("KVM: X86: Remove
unnecessary GFP_KERNEL_ACCOUNT for temporary variables").

Fixes: 8d032b683c ("KVM: TDX: create/destroy VM structure")
Fixes: a50f673f25 ("KVM: TDX: Do TDX specific vcpu initialization")
