virgl: adjust strides when mapping temp-resources

Browse source 
When we're mapping temp-resources, we clip the resource to the
transfer-box, which means the stride might not be correct any more.

So let's update the stride from the temp-resource, and recompute the
layer-stride.

This fixes crashes when running dEQP with --deqp-gl-config-name=rgba8888d24s8ms4
