[PATCH 4.19 12/33] RDMA/qedr: Fix reporting QP timeout attribute

[Greg Kroah-Hartman]

From: Kamal Heib <kamalheib1@xxxxxxxxx>

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.

Fixes: cecbcddf6461 ("qedr: Add support for QP verbs")
