KVM: SVM: Fix tsc offset adjustment when running nested
commit 77b1ab1732feb5e3dcbaf31d2f7547c5229f5f3a upstream.
When svm_vcpu_load is called while the vcpu is running in
guest mode the tsc adjustment made there is lost on the next
emulated #vmexit. This causes the tsc running backwards in
the guest. This patch fixes the issue by also adjusting the
tsc_offset in the emulated hsave area so that it will not
get lost.
