Don't lose sight of the fact that the additional of the WQ_MEM_RECLAIM is to silence
a warning BECAUSE ipoib's workqueue is WQ_MEM_RECLAIM.  This happens while
rdmavt/hfi1 is doing a cancel_work_sync() for the work item used by the QP's send engine

The ipoib wq needs to be audited to see if it is in the data path for VM I/O.
