Fixed BUG#10537: Server crashes while loading data file into table through

                  procedure.
  by simply disabling 'load' in stored procedures, like it's already disabled
  for prepared statements. (They must be made "re-execution" safe before
  working with either PS or SP.)


mysql-test/r/sp-error.result:
  New test case for BUG#10537.
mysql-test/t/sp-error.test:
  New test case for BUG#10537.
sql/sql_yacc.yy:
  Disable LOAD in stored procedures (just as for prepared statements).
