btrfs/112: remove some tests for cloning inline extents

This test case, btrfs/112, tests that some clone operations that have a
range covering inline extents fail with either -EOPNOTSUPP or -EINVAL.
These cases were unsupported on btrfs because they used to lead to file
corruptions and were not trivial to implement.

But there's now a patchset that adds support for them, and the relevant
patch of that patchset has the following subject:

  "Btrfs: implement full reflink support for inline extents"

So just remove these tests from test case btrfs/112, since this test
case is about testing only the unsupported reflink operations. A new
test case that verifies that these cases now work, as long as some other
new cases, will follow in another patch.
