Subject: [PATCH net-next 5/6] net/mlx4_core: Adjust the schedule queue port in reset-to-init too

It's legal for drivers to provide the QP port through the
QPC schedule-queue field on the reset-to-init QP state change.

Add adjusting of the schedule queue port in the SRIOV wrapper
for that operation too.
