[media] mb86a20s: Fix estimate_rate setting

As reported by Dan Carpenter <dan.carpenter@oracle.com>:
        Smatch warnings:
        drivers/media/dvb-frontends/mb86a20s.c:644 mb86a20s_layer_bitrate() error: buffer overflow 'state->estimated_rate' 3 <= 3
What happens there is that estimate_rate index should be the layer
number, and not the guard interval.
