rcu: Remove the CONFIG_TINY_RCU ifdefs in rcutiny.h

Now that CONFIG_TINY_PREEMPT_RCU is no more, this commit removes
the CONFIG_TINY_RCU ifdefs from include/linux/rcutiny.h in favor of
unconditionally compiling the CONFIG_TINY_RCU legs of those ifdefs.

[ paulmck: Moved removal of #else to "Remove TINY_PREEMPT_RCU" as
  suggested by Josh Triplett. ]
