Michal Schmidt 0ea3acbc80 rcu/srcutiny: don't return before reenabling preemption 
Code after the return statement is dead. Enable preemption before
returning from srcu_drive_gp().

This will be important when/if PREEMPT_AUTO (lazy resched) gets merged.

Fixes: 65b4a59557 ("srcu: Make Tiny SRCU explicitly disable preemption")
