seq_id from the WED RRO indication is a 12-bit field (0-4095), but only
values up to MT7996_RRO_MAX_SESSION map into wed_rro.addr_elem[], which
has MT7996_RRO_ADDR_ELEM_LEN (128) entries. A larger session id computes
an out-of-bounds element index that is then read and, on a signature
mismatch, written. Reject an out-of-range session id.
