[Mesa-dev] [PATCH v2 22/24] anv: handle errors while allocating new binding table blocks

[Iago Toral Quiroga]

Also, we had a couple of instances in flush_descriptor_sets() were
we were returning a VkResult directly upon error, but the return
value of this function is not a VkResult but a uint32_t dirty mask,
so simply return 0 in these cases which reduces the amount of
work the driver will do after the error has been raised.
