[ofa-general] [PATCH] opensm/osm_switch.h: use updated LFT for routing

[Yevgeny Kliteynik]

Hi Sasha,

Function osm_switch_get_port_by_lid() was using the switch's
LFT, so this LFT might not be updated to recent routing.

I think that this was also relevant before the LFT simplification.
One immediate outcome of this bug is opensm.fdbs file - when it
is dumped from the switch LFT (and not from lft_buf), it sometimes
doesn't match the lst file.
