Fixed LP bug #923236.

Browse Source 
When working on MWL#247 I forgot to adjust the function create_hj_key_for_table()
that created a key definition for hash join keys. The modified function must
set the values of the fields ext_key_parts, ext_key_flags, ext_key_part_map
added to the key definition structure in MWL#247.
