[PATCH 3/3] x86/resctrl: Clean up unused function parameter in rmdir path

[Xiaochen Shen]

Previous commit
("x86/resctrl: Remove superfluous kernfs_get() calls to prevent refcount leak")

removed superfluous kernfs_get() calls in rdtgroup_ctrl_remove() and
rdtgroup_rmdir_ctrl(). That change resulted in an unused function
parameter to these two functions.

Clean up the unused function parameter in rdtgroup_ctrl_remove(),
rdtgroup_rmdir_mon() and their callers rdtgroup_rmdir_ctrl() and
rdtgroup_rmdir().
