When the "rcupdate.rcu_self_test = 1" is set in bootargs and CONFIG_SRCU
option is enabled, the early_srcu will be tested, currently, for TREE SRCU,
if "srcutree.convert_to_big = 1" is set, the srcu_node structure will be
allocated at invoke init_srcu_struct_fields() time, after the test is
completed, the early_srcu will not be used.
Therefore, this commit invoke cleanup_srcu_struct() to release srcu_node
structure.
