workqueue: move struct worker definition to workqueue_internal.h
This will be used to implement an inline function to query whether %current is a workqueue worker and, if so, allow determining which work item it's executing. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Linus Torvalds <torvalds@linux-foundation.org>
