Review Comment:
ble_ll_sync_parse_biginfo_to_ev
also parameters should be biginfo pointer and length, it does not make sense
to pass acad and offset and calculate biginfo pointer over and over again

Review Comment:
no need to keep offset in sm, `ble_ll_sync_check_acad` is called from
`ble_ll_sync_rx_pkt_in` so it can just return pointer to biginfo and biginfo
length

`biginfo` and `biginfo_len` instead of `acad`
