rcu: Add synchronize_srcu_expedited()
This patch creates a synchronize_srcu_expedited() that uses
synchronize_sched_expedited() where synchronize_srcu()
uses synchronize_sched(). The synchronize_srcu() and
synchronize_srcu_expedited() functions become one-liners that
pass synchronize_sched() or synchronize_sched_expedited(),
repectively, to a new __synchronize_srcu() function.
While in the file, move the EXPORT_SYMBOL_GPL()s to immediately
follow the corresponding functions.
