Dept would skip check for dmaps marked by dept_map_nocheck() permanently.
However, sometimes it needs to skip check for some dmaps temporarily and
back to normal, for instance, lock acquisition with a nest lock.
Lock usage check with regard to nest lock could be performed by Lockdep,
however,
Workqueue already provides concurrency control. By that, any wait in a
work doesn't prevents events in other works with the control enabled.
Thus, each work would better be considered a different context.
So let Dept assign a different context id to each work.
