[PATCH tip/core/rcu 3/6] srcu: Unconditionally embed struct lockdep_map

[Paul E. McKenney]

From: Frederic Weisbecker <frederic@xxxxxxxxxx>

Since struct lockdep_map has zero size when CONFIG_DEBUG_LOCK_ALLOC=n,
this commit removes the #ifdef from the srcu_struct structure's ->dep_map.
This change will simplify further manipulations of this field.
