ksmbd: auth: fix most kernel-doc warnings

Fix 12 of 17 kernel-doc warnings in auth.c:

auth.c:221: warning: Function parameter or member 'conn' not described in 'ksmbd_auth_ntlmv2'
auth.c:221: warning: Function parameter or member 'cryptkey' not described in 'ksmbd_auth_ntlmv2'

auth.c:305: warning: Function parameter or member 'conn' not described in 'ksmbd_decode_ntlmssp_auth_blob'
auth.c:305: warning: Excess function parameter 'usr' description in 'ksmbd_decode_ntlmssp_auth_blob'

auth.c:385: warning: Function parameter or member 'conn' not described in 'ksmbd_decode_ntlmssp_neg_blob'
auth.c:385: warning: Excess function parameter 'rsp' description in 'ksmbd_decode_ntlmssp_neg_blob'
auth.c:385: warning: Excess function parameter 'sess' description in 'ksmbd_decode_ntlmssp_neg_blob'
auth.c:413: warning: Function parameter or member 'conn' not described in 'ksmbd_build_ntlmssp_challenge_blob'

auth.c:413: warning: Excess function parameter 'sess' description in 'ksmbd_build_ntlmssp_challenge_blob'

The other 5 are only present when a W=1 kernel build is done or
when scripts/kernel-doc is run with -Wall. They are:

auth.c:81: warning: No description found for return value of 'ksmbd_gen_sess_key'
auth.c:385: warning: No description found for return value of 'ksmbd_decode_ntlmssp_neg_blob'
auth.c:413: warning: No description found for return value of 'ksmbd_build_ntlmssp_challenge_blob'
auth.c:577: warning: No description found for return value of 'ksmbd_sign_smb2_pdu'
auth.c:628: warning: No description found for return value of 'ksmbd_sign_smb3_pdu'
