Remove the __exit annotation from VMX/SVM's hardware_unsetup(), the hook
can be reached during kvm_init() by way of kvm_arch_hardware_unsetup()
if failure occurs at various points during initialization.

Note, there is no known functional issue with the __exit annotation, the
above is merely justification for its removal.  The real motivation is
to be able to annotate vmx_x86_ops and svm_x86_ops with __initdata,
which makes objtool complain because objtool doesn't understand that the
vendor specific __initdata is being copied by value to a non-__initdata
