net: phy: mscc: fix macsec key length

Browse source

[ Upstream commit c309217f91 ]

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).
