macsec: validate ICV length on link creation

Browse source

Test the cipher suite initialization in case ICV length has a value
different than its default. If this test fails, creation of a new macsec
link will also fail. This avoids situations where further security
associations can't be added due to failures of crypto_aead_setauthsize(),
caused by unsupported user-provided values of the ICV length.
