drm/xe/configfs: Fix 'parameter name omitted' errors

On some configs and old compilers we can get following build errors:

  ../drivers/gpu/drm/xe/xe_configfs.h: In function 'xe_configfs_get_ctx_restore_mid_bb':
  ../drivers/gpu/drm/xe/xe_configfs.h:40:76: error: parameter name omitted
   static inline u32 xe_configfs_get_ctx_restore_mid_bb(struct pci_dev *pdev, enum xe_engine_class,
                                                                            ^~~~~~~~~~~~~~~~~~~~
  ../drivers/gpu/drm/xe/xe_configfs.h: In function 'xe_configfs_get_ctx_restore_post_bb':
  ../drivers/gpu/drm/xe/xe_configfs.h:42:77: error: parameter name omitted
   static inline u32 xe_configfs_get_ctx_restore_post_bb(struct pci_dev *pdev, enum xe_engine_class,
                                                                             ^~~~~~~~~~~~~~~~~~~~
when trying to define our configfs stub functions. Fix that.
