Subject: [PATCH] Avoid attaching NULL buffer while hiding EGL windows

Incremental fix for QTBUG-46921. Destroying the callback for NULL surface is not
working all the time. If the window is hidden by destroying the EGL surface
and hence setting the NULL buffer is no longer required.

Task-number:QTBUG-47902
