Fill defined view parts
SYNOPSIS
fill_defined_view_parts()
thd current thread.
view view to operate on
DESCRIPTION
This function will initialize the parts of the view
definition that are not specified in ALTER VIEW
to their values from CREATE VIEW.
The view must be opened to get its definition.
We use a copy of the view when opening because we want
to preserve the original view instance.

TRUE can't open table
