commit 118f767413ada4eef7825fbd4af7c0866f883441 upstream.
Make sure to save the passed QP timeout attribute when the QP gets modified, so when calling query QP the right value is reported and not the converted value that is required by the firmware. This issue was found while running the pyverbs tests.
