[Development] Segmentation fault with qpa directfb when upgrade qt5.2

[Nancy Zou]

Dear Thiago

As I have mentioned in QTBUG-40641,  I think the root cause is the function QDirectFbIntegration::initialize() was called two times. Since the Qtcore will call it, the original code in 
QDirectFbIntegrationPlugin::create() should be deleted.  Do you think is it reasonable?

Could Qt change the code to fix the bug ? 

Thank you.

Best Regards
Nancy
