cifs: zero-range does not require the file is sparse
Remove the conditional to fail zero-range if the file is not flagged as sparse. You can still zero out a range in SMB2 even for non-sparse files. Tested with stock windows16 server. Fixes 5 xfstests (033, 149, 155, 180, 349) Signed-off-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
