master: vkcube on Braswell

Vulkan KMS rendering breaks with commit 818b8579145196c7a8d4095bd5e65367e02a8fef

I could reproduce the crash on Haswell, Braswell and Skylake with vkcube and vkmark.
https://github.com/krh/vkcube
https://github.com/vkmark/vkmark

kmscube still works, the issue is limited to Vulkan.

I produced backtraces at the following commits, which are different.

818b8579145196c7a8d4095bd5e65367e02a8fef First bad
d6d2b6b5ec9b1638c0827582872670c7da79bb53 17.2.1
df8767a14e3eae4dcb8241b731b34e9379706795 Master 

On some platforms in some commits stash smashing is detected:
*** stack smashing detected ***: <unknown> terminated

vkmark does not always crash, look for SIGINT in the backtraces where it just froze.
