Peter Dillinger 442bd69222 Fix false NotFound from batched MultiGet with kHashSearch (#6821) 
Summary:
The error is assigning KeyContext::s to NotFound status in a
table reader for a "not found in this table" case, which skips searching
in later tables, like only a delete should. (The hash search index iterator
is the only one that can return status NotFound even if Valid() == false.)

This was detected by intermittent failure in
MultiThreadedDBTest.MultiThreaded/5, a kHashSearch configuration.

Test Plan: modified existing unit test to reproduce problem
