glsl: Fix usage of the wrong union member in program_resource_visitor::recursion.

glsl: Fix usage of the wrong union member in program_resource_visitor::recursion.

In the array-of-struct case, recursion() takes the row_major flag for
each iteration from 't->fields.structure[i]', but 't' is not a record
type.  Inherit the array declaration row_major flag instead.

This mistake was found by running piglit on valgrind.
