Fixed BUG#13683: INSERT DELAYED into a view creates an infinite loop.

Browse Source 
The bug was caused by wrong behaviour of mysql_insert() which in case
 of INSERT DELAYED into a view exited with thd->net.report_error == 0.
 This blocked error reporting to the client which started waiting
 infinitely for response to the query.


mysql-test/r/insert.result:
  Fixed results for the added test case.
mysql-test/t/insert.test:
  Added test case.
sql/sql_insert.cc:
  Fixed BUG#13683: INSERT DELAYED into a view creates an infinite loop.
   Changed mysql_insert(): delayed_get_table() applied to a view exits
   with ER_WRONG_OBJECT error (and with thd->net.report_error == 1) and
   in this case we must just exit from mysql_insert().  Prior to this
   change, instead of exiting open_and_lock_tables() was invoked which
   cleared thd->net.report_error to zero and caused the bug.
