699ce097efe ("workqueue: implement and use pwq_adjust_max_active()")
replaced the only workqueue_freezing usage outside freezer callbacks
with a POOL_FREEZING test.  This makes workqueue_freezing unused when
!CONFIG_FREEZER leading to a compiler warning.  Define
workqueue_freezing iff CONFIG_FREEZER.
