Revert "s3-winbind: Fix schannel connections against trusted domain DCs"

This reverts commit d2379caa77fe02264323d69fee1bcad33f1bfeee.

This change doesn't solve the real problem, it just
causes useless network traffic and the following error:

rpccli_setup_netlogon_creds failed for W2012R2-L6, unable to setup NETLOGON
credentials: NT_STATUS_NO_TRUST_SAM_ACCOUNT

While the old logic caused NT_STATUS_CANT_ACCESS_DOMAIN_INFO (without
network traffic) instead of the NT_STATUS_NO_TRUST_SAM_ACCOUNT.

A better fix will follow.
