[PATCH] opensm/osm_sa_path_record.c: validate multicast membership

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

When PathRecord query has multicast destination and SLID and/or SGID is
specified we need to ensure that this path source port is member of the
destination multicast group.
