MW-86 Removed unnecessary wsrep_sync_wait before processing SQLCOM_REPLACE

sciascid · Jan Lindström · commit f81d9ef108b1 · 2017-08-14T12:00:09.000+03:00
Sync waiting before processing SQLCOM_REPLACE was not necessary given that
this case falls through to processing of SQLCOM_INSERT. In case of
SQLCOM_REPLACE, wsrep_sync_wait would be called twice.
