From: Filipe Manana <fdmanana@xxxxxxxx>
Currently the test fails when we pass "-o nodatasum" in MOUNT_OPTIONS and
the reason is because we enable compression, with "chattr +c", on a file
and then try to clone from it to a file with nodatasum inherited from the
mount options, which results in the clone ioctl to fail with -EINVAL since
it's not possible to clone from datasum to nodatasum and vice-versa.
So skip the test if nodatasum is a mount option.
