Paul E. McKenney 39c0bbfc07 rcu: Eliminate local variable lastcomp from force_quiescent_state() 
Because rsp->fqs_active is set to 1 across
force_quiescent_state()'s switch statement, rcu_start_gp() will
refrain from starting a new grace period during this time.
Therefore, rsp->gpnum is constant, and can be propagated to all
uses of lastcomp, eliminating this local variable.
