[PATCH 5.17 031/772] cifs: when extending a file with falloc we should make files not-sparse

commit f66f8b94e7f2f4ac9fffe710be231ca8f25c5057 upstream.
as this is the only way to make sure the region is allocated.
Fix the conditional that was wrong and only tried to make already
non-sparse files non-sparse.
