Make the extent buffer allocation interface consistent. Cloned eb will
set a valid fs_info. For dummy eb, we can drop the length parameter and
set it from fs_info.
The built-in sanity checks may pass a NULL fs_info that's queried for
nodesize, but we know it's 4096.

While looking at somebodys corruption I became completely convinced that
btrfs_split_item was broken, so I wrote this test to verify that it was working
as it was supposed to. Thankfully it appears to be working as intended, so just
add this test to make sure nobody breaks it in the future. Thanks,
