QHeaderView - minor cleanup in viewportEvent

Browse Source 
This is an improvement to a previous fix with
SHA e62e71162606fec134600955a89b7e0c34a7840b

We actually never want to call resizeSections if the parent is hidden.
Therefore we can both simplify and improve the code with this patch.

When we do show/hide on parent then the visible status is updated
before we get into this code. I have verified the patch on the code
from:

Task-number: QTBUG-14234
