[PATCH v7 1/4] drm/xe/vf: Update pause/unpause() helpers with VF naming

[Raag Jadav <raag.jadav@intel.com>]

Now that pause/unpause() helpers have been updated for VF migration
usecase, update their naming to match the functionality and while at it,
add IS_SRIOV_VF() assert to make sure they are not abused.

v7: Add IS_SRIOV_VF() assert (Matthew Brost)
    Use "vf" suffix (Michal)
