x86/resctrl: Factor rdtgroup lock for multi-file ops
rdtgroup_kn_lock_live() can only release a kernfs reference for a single
file before waiting on the rdtgroup_mutex, limiting its usefulness for
operations on multiple files, such as rename.
Factor the work needed to respectively break and unbreak active
protection on an individual file into rdtgroup_kn_{get,put}().
No functional change.
