net: atlantic: fix the macsec key length
The key length used to store the macsec key was set to MACSEC_KEYID_LEN
(16), which is an issue as:
- This was never meant to be the key length.
- The key length can be > 16.
Fix this by using MACSEC_MAX_KEY_LEN instead (the max length accepted in
uAPI).
Fixes: 27736563ce32 ("net: atlantic: MACSec egress offload implementation")
Fixes: 9ff40a751a6f ("net: atlantic: MACSec ingress offload implementation")
