Because rcu_eqs_special_set() is declared only in internal header
kernel/rcu/tree.h and stubbed in include/linux/rcutiny.h, it is
inaccessible outside of the RCU implementation. This patch therefore
moves the rcu_eqs_special_set() declaration to include/linux/rcutree.h,
which allows it to be used in non-rcu kernel code.
