wifi: lib80211: Handle const struct lib80211_crypto_ops in lib80211

Browse Source 
lib80211_register_crypto_ops() and lib80211_unregister_crypto_ops() don't
modify their "struct lib80211_crypto_ops *ops" argument. So, it can be
declared as const.

Doing so, some adjustments are needed to also constify some date in
"struct lib80211_crypt_data", "struct lib80211_crypto_alg" and the
return value of lib80211_get_crypto_ops().
