Validation errors in extended dynamic state2 sample

[SaschaWillems]

While working on #1406 I noticed that the extended dynamic state2 sample displays the following validation errors with a recent SDK:

[error] 853490033 - UNASSIGNED-Draw-primitiveTopologyPatchListRestart: vkCmdDrawIndexed(): the last call to vkCmdSetPrimitiveTopology is VK_PRIMITIVE_TOPOLOGY_PATCH_LIST, the primitiveTopologyPatchListRestart feature was not enabled, but vkCmdSetPrimitiveRestartEnable last set primitiveRestartEnable to VK_TRUE.

They're repeated multiple times.

We need to fix those.
