IB/ipath: Fix lost UD send work request

Browse source

If a UD QP has some work requests queued to be sent by the DMA engine
followed by a local loopback work request, we have to wait for the
previous work requests to finish or the completion for the local
loopback work request would be generated out of order.  The problem
was that the work request queue pointer was already updated so that
the request would not be processed when the DMA queue drained.
