srcu: Apply trivial callback lists to shrink Tiny SRCU
The rcu_segcblist structure provides quite a bit of functionality, and Tiny SRCU needs almost none of it. So this commit replaces Tiny SRCU's uses of rcu_segcblist with a simple singly linked list with tail pointer. This change significantly reduces Tiny SRCU's memory footprint, more than making up for the growth caused by the creation of rcu_segcblist.c Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
