[PATCH] ieee802154: ca8210: Drop spurious WQ_UNBOUND from alloc_ordered_workqueue() call

[Tejun Heo]

Workqueue is in the process of cleaning up the distinction between unbound
workqueues w/ @nr_active==1 and ordered workqueues. Explicit WQ_UNBOUND
isn't needed for alloc_ordered_workqueue() and will trigger a warning in the
future. Let's remove it. This doesn't cause any functional changes.

Looks okay to me.
