KVM: SVM: fix guest global tlb flushes with NPT
(cherry picked from commit e5eab0cede4b1ffaca4ad857d840127622038e55)
Accesses to CR4 are intercepted even with Nested Paging enabled. But the code
does not check if the guest wants to do a global TLB flush. So this flush gets
lost. This patch adds the check and the flush to svm_set_cr4.
