btrfs: tests: fix error messages for test case 4 of extent map tests

In test case 4 for extent maps, if we error out we are supposed to print
in interval but instead of printing a non-inclusive end offset, we are
printing the length of the interval, which makes it confusing. So fix
that to print the exclusive end offset instead.
