fs/ntfs3: Keep prealloc for all types of files

Browse Source 
Before we haven't kept prealloc for sparse files because we thought that
it will speed up create / write operations.
It lead to situation, when user reserved some space for sparse file,
filled volume, and wasn't able to write in reserved file.
With this commit we keep prealloc.
Now xfstest generic/274 pass.
Fixes: be71b5cba2 ("fs/ntfs3: Add attrib operations")
