rcu: Initialize multi-level RCU grace periods holding locks
Prior implementations initialized the root and any internal
nodes without holding locks, then initialized the leaves
holding locks.
This is a false economy, as the leaf nodes will usually greatly
outnumber the root and internal nodes. Acquiring locks on all
nodes is conceptually much simpler as well.
