[PATCH 5.15 029/667] cifs: when extending a file with falloc we should make files not-sparse

[Greg Kroah-Hartman]

From: Ronnie Sahlberg <lsahlber@xxxxxxxxxx>

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.
