Georges Basile Stavracas Neto 0b2006b74f vulkan/image: Set HOST and TRANSFER bits for before barriers
Multiple images in the before barrier array are defined with
VK_ACCESS_TRANSFER_WRITE_BIT and VK_ACCESS_TRANSFER_READ_BIT,
which requires passing VK_PIPELINE_STAGE_TRANSFER_BIT and
VK_PIPELINE_STAGE_HOST_BIT to vkCmdPipelineBarrier().

Pass these flags correctly.
