KVM: fix error handling for out of range irq
find_index_from_host_irq returns 0 on error but callers assume < 0 on error. This should not matter much: an out of range irq should never happen since irq handler was registered with this irq #, and even if it does we get a spurious msix irq in guest and typically nothing terrible happens. Still, better to make it consistent. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
