This actually fixes crashes due to stale pointers.
With multi-channel and with 2 (or more) connections,
we'll call smbXsrv_session_disconnect_xconn() when a connection
gets disconnected, but we'll leave smbXsrv_client and all other
connections in place.
However smbXsrv_session_disconnect_xconn_callback() left
a stale session->db_rec pointer in place, which means
a following smbXsrv_session_logoff() will call
dbwrap_record_delete(local_rec) on a stale pointer.

Before merging the s3 and s4 RPC servers the rpcint_dispatch function
was not logging any error.
This commit lowers from DBG_ERR to DBG_INFO the importance of error
messages when dispatching local RPC calls. There are some situations
where RPC functions return RPC faults and this is not a fatal condition.
One example is _lsa_QueryInfoPolicy2.
This change prevents a noisy error logged when winbindd tries to connect to
its primary domain in the nt4_member and ad_member test environments:

Before merging the s4 and s3 RPC servers the make_internal_rpc_pipe_p()
function did not fail when the requested interface was not registered in
the calling process because it did not check the return value of
rpc_srv_get_pipe_cmds(). If the interface was not registed, the pointer
to the interface functions was NULL and later, when dispatching a call,
rpcint_dispatch() returned NT_STATUS_RPC_PROCNUM_OUT_OF_RANGE in this
case.
After merging the RPC servers, the rpc_pipe_open_internal() function
will return NT_STATUS_RPC_INTERFACE_NOT_FOUND if the interface is not
registered in the calling process. This causes a noisy error message in
winbind when it tries to open the dssetup pipe to the primary domain and
it is not an AD domain.
The callers of wb_open_internal_pipe() when connecting to the domain
already logs the error at level greather or equal to five. This commit
moves the dupplicated and noisy error message at level zero from
wb_open_internal_pipe() to its callers outside winbindd_cm.c.
This error can be seen in winbindd logs of ad_member and nt4_member test
environments.
