KVM: SVM: Fix nested VM-Exit on #GP interception handling
Fix the interpreation of nested_svm_vmexit()'s return value when synthesizing a nested VM-Exit after intercepting an SVM instruction while L2 was running. The helper returns '0' on success, whereas a return value of '0' in the exit handler path means "exit to userspace". The incorrect return value causes KVM to exit to userspace without filling the run state, e.g. QEMU logs "KVM: unknown exit, hardware reason 0".
