Currently CQ poll returns an error if the QP
associated with a CQE is destroyed although
there can be more CQEs for other QPs which are
still active. Fix this by skipping the CQE for
the destroyed QP and continue with CQE processing.
The patch is similar to driver commit f8a4e76c75e5
("RDMA/i40iw: Fix for checking if the QP is destroyed")
Fixes: faf6782ac8bc ("libi40iw: Initial public release of libi40iw-0.5.223")
