anv/pass: Store the depth-stencil attachment's last subpass index

Commit 968ffd6c868af7226e8f889573eef709888151cb stored the last subpass
index of all the attachments but that of the depth-stencil attachment.
This could cause depth buffers used in multiple subpasses not to be in
the requested final layout. Fix this error.
