workqueue: remove in_workqueue_context()
Commit a25909a4 (lockdep: Add an in_workqueue_context() lockdep-based test function) added in_workqueue_context() but there hasn't been any in-kernel user and the lockdep annotation in workqueue is scheduled to change. Remove the unused function. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
