[PATCH] libibnetdiscover: more outstanding MADs counting fix

[Sasha Khapyorsky <sashak-smomgflXvOZWk0Htik3J/w@public.gmane.org>]

Decrease outstanding MADs counter before calling process_smp_queue()
and smp receive callback, so that there will be room available for
sending more MADs. This fixes 'ibnetdiscover -o 1' (max outstanding
SMPs on a wire = 1) bug.
