From: Shlomo Pongratz <shlo...@mellanox.com>
For QPs of type IB_QPT_XRC_TGT the IB core assigns a common event handler
__ib_shared_qp_event_handler, and the optionally supplied event handler
is stored. When the common handler is called it iterates on all opened
QPs and calles the original handlers without checking if they are
NULL, fix that.
