flush_work_sync is equivalent to flush_work.

Browse Source 
v3.15-rc1-6-g1a56f2aa4752 removes flush_work_sync entirely, but
ever since v3.6-rc1-25-g606a5020b9bd which made all workqueues
non-reentrant, it has been equivalent to flush_work.

This is safe because in all cases only one server->work can be
in flight at a time.
