Fixed behavior of LOAD DATA with subqueries in SET clause.

Browse Source 
The idea is to use TABLE_LIST::lock_type for passing type of lock for
target table to mysql_load() instead of using LEX::lock_option 
(which were rewritten by first subselect in SET clause).

This should also fix potential problem with LOAD DATA in SP
(it is important for them to have right lock_type in the table
 list by the end of statement parsing).
