RDMA/irdma: Drop spurious WQ_UNBOUND from alloc_ordered_workqueue() call

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.
