ada: Fix small inaccuracy in previous change
The call to Build_Allocate_Deallocate_Proc must occur before the special
accessibility check for class-wide allocation is generated, because this
check comes with cleanup code.
gcc/ada/
* exp_ch4.adb (Expand_Allocator_Expression): Move the first call to
Build_Allocate_Deallocate_Proc up to before the accessibility check.
