anv: Handle UNDEFINED format in image format list

It's not invalid to have this value in the list, but the only case it
is actually valid as format in the creation of an image or image view
is with Android Hardware Buffers which have their format specified
externally.

So we can just ignore all entries with VK_FORMAT_UNDEFINED.
