    crypto: clarify name of WEAK_KEY request flag · 231baecd

    CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
    sounds like it is requesting a weak key.  Actually, it is requesting
    that weak keys be forbidden (for algorithms that have the notion of
    "weak keys"; currently only DES and XTS do).
    
    Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
    it can be easily confused.  (This in fact happened in the UX500 driver,
    though just in some debugging messages.)
    
    Therefore, make the intent clear by renaming it to
    CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.
