[PATCH] fix CM compilation for gcc 2.95 (was Re: [openib-general] RFC on SDP checkin)

[Roland Dreier]

gcc 2.95 fails on the current tree with

    cm.c:140: field `path' has incomplete type

Unfortunately, although the C spec says that using just "[]" to
declare arrays at the end of a struct is correct, gcc 2.95 insists on
"[0]".  This patch makes that change.
