Several leaks and issues were found when running iWARP with kmemleak. some apply to RoCE as well. This series fixes some memory leaks and some wrong methods of synchronization which were used to wait for iWARP CM related events. Changes from v1 --------------- - When removing the qp from the xarray xa_erase should be used and not xa_erase_irq as this can't be called from irq context. - Add xa_lock around loading a qp from the xarray and increase the refcnt only under the xa_lock and only if not zero. This is to make qedr more robust and not rely on the core/iwcm implementation to assure correctness. - Complete the iwarp_cm_comp event only if the bit was turned on and the destroy qp flow will attempt to look at the completion.
