rcu: Remove obsolete force-quiescent-state statistics for debugfs
The debugfs interface displayed statistics on RCU-pending checks but this interface has since been removed. This commit therefore removes the no-longer-used rcu_state structure's ->n_force_qs_lh and ->n_force_qs_ngp fields along with their updates. (Though the ->n_force_qs_ngp field was actually not used at all, embarrassingly enough.) If this information proves necessary in the future, the corresponding event traces will be added.
