kernfs: switch global kernfs_idr_lock to per-fs lock
The kernfs implementation has big lock granularity(kernfs_idr_lock) so
every kernfs-based(e.g., sysfs, cgroup) fs are able to compete the lock.
This patch switches the global kernfs_idr_lock to per-fs lock, which
put the spinlock into kernfs_root.
