anv: Query the kernel for reset status

Browse Source 
When a client causes a GPU hang (or experiences issues due to a hang in
another client) we want to let it know as soon as possible.  In
particular, if it submits work with a fence and calls vkWaitForFences or
vkQueueQaitIdle and it returns VK_SUCCESS, then the client should be
able to trust the results of that rendering.  In order to provide this
guarantee, we have to ask the kernel for context status in a few key
locations.
