[ofa-general] [PATCH] opensm: switch LFTs incremental update fix

[Sasha Khapyorsky]

When switch is discovered first time its port links could be already
initialized by previous SM, so in this case LFTs update must be enforced
in order to overwrite an "old junk". This patch enforces sw->need_update
flag when switch is found first time.
