[ Upstream commit dc52aadbc1849cbe3fcf6bc54d35f6baa396e0a1 ]
Commit 21c2fe94abb2 ("RDMA/mthca: Combine special QP struct with mthca QP")
introduced a new struct mthca_sqp which doesn't contain struct mthca_qp
any longer. Placing a pointer of this new struct into qptable leads
to crashes, because mthca_poll_one() expects a qp pointer. Fix this
by putting the correct pointer into qptable.
