KVM: VMX: Don't bother disabling eVMCS static key on module exit
[ Upstream commit da66de44b01e9b7fa09731057593850394bf32e4 ]
Don't disable the eVMCS static key on module exit, kvm_intel.ko owns the
key so there can't possibly be users after the kvm_intel.ko is unloaded,
at least not without much bigger issues.
