Now that workqueue can handle work item queueing from very early
during boot, there is no need to delay schedule_work() while
!keventd_up().  Remove it.

Hello,

This change depends on an earlier workqueue patch and is followed by a
patch to remove keventd_up().  It'd be great if it can be routed
through the wq/for-4.9 branch.

Thanks.
