AES-CCM decryption.

• pt - Plaintext.
• tag - Authentication tag.
• tag_len - Tag length (4, 6, 8, 10, 12, 14, or 16).
• ct - Ciphertext.
• ct_len - Ciphertext length, 0 <= * ct_len - < 2^(8*(15-n_len)).
• key - AES key.
• size - Key size (16, 24, or 32).
• nonce - Nonce.
• n_len - Nonce length, 7 <= * n_len - <= 13.
• aa - Additional authentication data.
• aa_len - Additional authentication data length.

Returns 0 If * tag - is valid. Returns -1 Otherwise.

@remark * ct - may be same as * pt - .
