KVM: VMX: Fix cr8 exiting control clobbering by EPT
(cherry picked from commit 5fff7d270bd6a4759b6d663741b729cdee370257)
Don't call adjust_vmx_controls() two times for the same control.
It restores options that were dropped earlier. This loses us the cr8
exit control, which causes a massive performance regression Windows x64.
