IB/ipoib: Change list_del to list_del_init in the tx object
BugLink: http://bugs.launchpad.net/bugs/1732698 [ Upstream commit 27d41d29 ] Since ipoib_cm_tx_start function and ipoib_cm_tx_reap function belong to different work queues, they can run in parallel. In this case if ipoib_cm_tx_reap calls list_del and release the lock, ipoib_cm_tx_start may acquire it and call list_del_init on the already deleted object. Changing list_del to list_del_init in ipoib_cm_tx_reap fixes the problem.
