srcu: Dynamically allocate srcu_node array
This commit shrinks the srcu_struct structure by converting its ->node
field from a fixed-size compile-time array to a pointer to a dynamically
allocated array. In kernels built with large values of NR_CPUS that boot
on systems with smaller numbers of CPUs, this can save significant memory.
