KVM: SVM: Return correct values in nested_svm_exit_handled_msr
The nested_svm_exit_handled_msr() returned an bool which is a bug. I worked by accident because the exected integer return values match with the true and false values. This patch changes the return value to int and let the function return the correct values. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
