[Mesa-stable] [PATCH 4/4] anv: Handle VK_WHOLE_SIZE properly for buffer views

[Jason Ekstrand]

The old calculation, which used view->offset, encorporated buffer->offset
into the size calculation where it doesn't belong.  This meant that, if
buffer->offset > buffer->size, you would always get a negative size.  This
fixes 170 dEQP-VK.renderpass.attachment.* Vulkan CTS tests on Haswell.
