Needed for lightweight and modular internal/pci error handling.
Implement sriov attach function which enables pre-saved number of vfs on
the device side.
Implement sriov detach function which disable the current vfs on the
device side.
Init/cleanup function only handles sriov software context allocation and
destruction.
