mem-ruby: fix the condition for stale WriteCleanFull

WriteCleanFull can be requested for the cache line in SD state (e.g.
Local eviction of a cache line in SD_RSC state). In this case, the
requestor is the owner of the cache line,
but it doesn't have it with exclusive right.
Thus, 'ownerIsExcl == false' should be removed from the stale condition.
