[ofa-general] [PATCH] opensm: do not configure MFTs when mcast support is disabled

[Yevgeny Kliteynik]

Hi Sasha,

I noticed that when MCast support in OSM is disabled (command line
option '-d3'), MFTs on the switches are still getting configured.

Turns out that MFTs configuration was disabled only in heavy sweep,
but it was still working at idle time - the following patch fixes it.
