vulkan: Use the right flags

Somebody (me) had flipped the 2 flags in commit ba28971a183:

[ VUID-vkCmdCopyBufferToImage-srcBuffer-00174 ] Object 0: handle = 0x3cfaac0, type = VK_OBJECT_TYPE_COMMAND_BUFFER; Object 1: handle = 0x430000000043, type = VK_OBJECT_TYPE_BUFFER; | MessageID = 0xe1b276a1 | Invalid usage flag for VkBuffer 0x430000000043[] used by vkCmdCopyBufferToImage. In this case, VkBuffer should have VK_BUFFER_USAGE_TRANSFER_SRC_BIT set during creation. The Vulkan spec states: srcBuffer must have been created with VK_BUFFER_USAGE_TRANSFER_SRC_BIT usage flag (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-vkCmdCopyBufferToImage-srcBuffer-00174)
