s3-ntlmssp Remove unused ntlmssp_set_hashes() and do not set an invalid LM hash

When E_deshash() returns false, it indicates that the password is either > 14 chars
in length, or could not be represented as an LM hash value for some other
reason.  In this case, we should not regard the LM hash being missing
as an error or a no-password situation.
