Tom Lendacky ed02b21309 KVM: SVM: Guest FPU state save/restore not needed for SEV-ES guest ...

The guest FPU state is automatically restored on VMRUN and saved on VMEXIT
by the hardware, so there is no reason to do this in KVM. Eliminate the
allocation of the guest_fpu save area and key off that to skip operations
related to the guest FPU state.
