kernfs: Clarify lockdep name for kn->count
The reference count in kernfs_node structure is treated like a rwsem by using lockdep instrumentation code. The lockdep name, however, is still "s_active" which is carried over from the old sysfs code. As s_active is no longer the variable name, its use may confuse users on where the lock is when it is reported by lockdep. So it is changed to "kn->count" which is how this variable is normally referenced in kernfs code.
