Don't crash on broken GIF images

Broken GIF images could set invalid width and height
values inside the image, leading to Qt creating a null
QImage for it. In that case we need to abort decoding
the image and return an error.

Initial patch by Rich Moore.

Backport of Id82a4036f478bd6e49c402d6598f57e7e5bb5e1e from Qt 5

Task-number: QTBUG-38367
Change-Id: I0680740018aaa8356d267b7af3f01fac3697312a
Security-advisory: CVE-2014-0190
