Subject: [PATCH tip/core/rcu 10/22] rcu: Remove needless initialization

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

For global variables, C defaults all fields to zero.  The initialization
of the rcu_state structure's ->n_force_qs and ->n_force_qs_ngp fields
is therefore redundant, so this commit removes these initializations.
