lavapipe: do not short-circuit AHB export alloc (non-import)

Browse source 
Per spec VUID-VkMemoryAllocateInfo-pNext-01874:

If the parameters do not define an import operation, and the pNext chain
includes a VkExportMemoryAllocateInfo structure with
VK_EXTERNAL_MEMORY_HANDLE_TYPE_ANDROID_HARDWARE_BUFFER_BIT_ANDROID
included in its handleTypes member, and the pNext chain includes a
VkMemoryDedicatedAllocateInfo structure with image not equal to
VK_NULL_HANDLE, then allocationSize must be 0

- before: total 116, skip 66, pass 36, fail 14
- after:  total 116, skip 66, pass 50, fail 0
