HBASE-20772 Controlled shutdown fills Master log with the disturbing message 'No matching procedure found for rit=OPEN, location=ZZZZ, table=YYYYY, region=XXXX transition to CLOSED' 

Look for the particular case where RS does the close of region w/o
involving Master and log special message in this case. Dodgy. But
until we have Master run shutdown of all regions, better than
the message we currently show.
