ksmbd: add support for key exchange
When mounting cifs client, can see the following warning message.
CIFS: decode_ntlmssp_challenge: authentication has been weakened as server
does not support key exchange
To remove this warning message, Add support for key exchange feature to
ksmbd. This patch decrypts 16-byte ciphertext value sent by the client
using RC4 with session key. The decrypted value is the recovered secondary
key that will use instead of the session key for signing and sealing.
