[ofw] [IPoIB CM] patch makes proprity for remotely initiated connection.

[Alex Estrin]

Linux ipoib cm always initiates connect request and prefer to use correlated RC QP.
Proposed patch will always use remotely initiated connection path (if any) to prevent possible race.
Please review.

Thanks,
Alex.
