enable fallocate punch hole ("fallocate -p") for SMB3
Implement FALLOC_FL_PUNCH_HOLE (which does not change the file size fortunately so this matches the behavior of the equivalent SMB3 fsctl call) for SMB3 mounts. This allows "fallocate -p" to work. It requires that the server support setting files as sparse (which Windows allows). Signed-off-by: Steve French <smfrench@gmail.com>
