fs/ntfs3: drop preallocated clusters for sparse and compressed files

[ Upstream commit 3a6aba7f3cf2b46816e08548c254d98de9c74eba ]

Do not keep preallocated clusters for sparsed and compressed files.
Preserving preallocation in these cases causes fsx failures when running
with sparse files and preallocation enabled.
