locking/osq_lock: Move the definition of optimistic_spin_node into osq_lock.c
struct optimistic_spin_node is private to the implementation. Move it into the C file to ensure nothing is accessing it. Signed-off-by: David Laight <david.laight@aculab.com> Acked-by: Waiman Long <longman@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
