[Alexander Gordeev]

Hello,

This is an attempt to make RCU tree initialization bit more
clear and optimize memory footprint of data associated with
the tree.

  rcu: Panic if RCU tree can not accommodate all CPUs
  rcu: Remove superfluous local variable in rcu_init_geometry()
  rcu: Cleanup rcu_init_geometry() code and arithmetics
  rcu: Simplify rcu_init_geometry() capacity arithmetics
  rcu: Limit rcu_state::levelcnt[] to RCU_NUM_LVLS items
  rcu: Limit rcu_capacity[] size to RCU_NUM_LVLS items
  rcu: Remove unnecessary fields from rcu_state structure
  rcu: Limit count of static data to the number of RCU levels
  rcu: Simplify arithmetic to calculate number of RCU nodes
