[openib-general] [PATCH] opensm: clean old references on ports linking

[Sasha Khapyorsky]

When linking ports, cleanup old remote references. Without it the ports
still be accessible as "linked" from old neighbors and in case of ports
moving, when some MADs can be lost or reordered, OpenSM subnet data
structures become broken.
