vfio/common: Propagate KVM_SET_DEVICE_ATTR error if any

Browse source 
In the VFIO_SPAPR_TCE_v2_IOMMU container case, when
KVM_SET_DEVICE_ATTR fails, we currently don't propagate the
error as we do on the vfio_spapr_create_window() failure
case. Let's align the code. Take the opportunity to
reword the error message and make it more explicit.
