bugfix: table->get_fields_in_item_tree=true

Browse Source 
partitioning was setting subj as a partitioning-specific
hack (GET_FIXED_FIELDS_FLAG field flag to detect partitioning fields)
inside init_lex_with_single_table(). But vcols also use
init_lex_with_single_table(), they run fix_fields()
in open_table_from_share() before partitioning and this messes up
partitioning GET_FIXED_FIELDS_FLAG logic.
