cifs: Cleanup and thus reduce smb session structure and fields used during authentication
Removed following fields from smb session structure cryptkey, ntlmv2_hash, tilen, tiblob and ntlmssp_auth structure is allocated dynamically only if the auth mech in NTLMSSP. response field within a session_key structure is used to initially store the target info (either plucked from type 2 challenge packet in case of NTLMSSP or fabricated in case of NTLMv2 without extended security) and then to store Message Authentication Key (mak) (session key + client response). Server challenge or cryptkey needed during a NTLMSSP authentication is now part of ntlmssp_auth structure which gets allocated and freed once authenticaiton process is done.
