hisi_acc_vfio_pci: extract public functions for container_of

Browse Source 
In the current driver, vdev is obtained from struct
hisi_acc_vf_core_device through the container_of function.
This method is used in many places in the driver. In order to
reduce this repetitive operation, It was extracted into
a public function.
