[Qemu-devel] hw/vfio/pci: duplicated invocation of vfio_msix_vector_release() in vfio_msix_disable()

[Guoheyi]

Hi folks,

Recently we found there are 2 invocations of vfio_msix_vector_release() 
in vfio_msix_disable(). The 1st one is in msix_unset_vector_notifiers(), 
for we set device's msix_vector_release_notifier to 
vfio_msix_vector_release() in vfio_msix_enable(), while the 2nd is the 
explicit one in vfio_msix_disable(). Both invocations switch VFIO to use 
the non-bypass eventfd.

Is there any special reason for doing this? Or can we remove one of them?

Thanks,

Heyi
