[PATCH mpam mpam/snapshot+extras/v6.18-rc1 v2 2/3] fs/resctrl: Remove unused 'of' parameter from rdtgroup_move_iommu()

[Zeng Heng]

The 'of' (kernfs_open_file) parameter in rdtgroup_move_iommu() is
not used within the function body. Remove it to simplify the
interface and eliminate the unnecessary argument passing.
