clients: Fix dmabuf feedback stall in simple-vulkan

Browse source 
When we receive dmabuf feedback, we hit the VK_SUBOPTIMAL path and
recreate the swapchain, returning early without submitting work.

However, we've already reset the fence before we do this, so we'll
block forever waiting for work that never comes to signal it.

Instead, we should reset the fence right before we know we're submitting
work.
