Bug Description
[Impact]
The recent SRU'd patch had a bug in it that caused a crash if xf86ModeVRefresh returned 0. Amend the patch to fix this.
[Test case]
Would need an affected system to test this on, but we haven't been able to reproduce this even on an identical system as on one of the reported errors (XPS 15 9560).
[Where things could go wrong]
This only adds a new check.
