Otherwise, we'd better split the series.When introducing features provisioning ability to ifcvf, there is a need to re-create vDPA devices on a VF with different feature bits. When remove a vDPA device, the container of struct vdpa_device (here is ifcvf_adapter) is free-ed in dev_del() interface, so we need to allocate ifcvf_adapter in dev_add() than in probe(). That's why I have re-factored the adapter/mgmt_dev code. For re-factoring the irq related code and ifcvf_base, let them work on struct ifcvf_hw, the reason is that the adapter is allocated in dev_add(), if we want theses functions to work before dev_add(), like in probe, we need them work on ifcvf_hw than the adapter.

Device could be deleted from the management device anyhow.
