mem-ruby: bug fix for stale WriteBack
Finish_CopyBack_Stale is scheduled only when the requestor is the last
sharer. This prevents the cacahe evicting the line which was already
evicted while the stale WriteBack transaction was stalled.
Wrong condition check in Finish_CopyBack_Stale for eviction is also
removed.
