autocommit=1 not resetting session->server_status properly when committing ongoing txn

[Stewart Smith]

from delete.test:

SET AUTOCOMMIT=0;
DELETE from t1;
SET AUTOCOMMIT=1;
drop table t1;

#
# Test of delete when the delete will cause a node to disappear and reappear
# (This assumes a block size of 1024)
#

create table t1 (
        a bigint not null,
        b bigint not null default 0,
        c bigint not null default 0,
        d bigint not null default 0,
        e bigint not null default 0,
        f bigint not null default 0,
        g bigint not null default 0,
        h bigint not null default 0,
        i bigint not null default 0,
        j bigint not null default 0,
        primary key (a,b,c,d,e,f,g,h,i,j));

with this in the create table path:
 if (session->inTransaction())
    {
      my_error(ER_TRANSACTIONAL_DDL_NOT_SUPPORTED, MYF(0));
      return true;
    }

throws an error when it shouldn't. (only create table has been modifide)
