Eli Cohen 1d368c5465 IB/ib_mthca: Pre-link receive WQEs in Tavor mode ...

We have recently discovered that Tavor mode requires each WQE in a
posted list of receive WQEs to have a valid NDA field at all times.
This requirement holds true for regular QPs as well as for SRQs.  This
patch prelinks the receive queue in a regular QP and keeps the free
list in SRQ always properly linked.
