[PATCH] Simple patch to quiet some messages in xc_domain.c

xc_domain.c has a few fprintfs producing information about some error
cases. These probably should be handled as debugging messages, and
this patch implements one approach to this. The affected APIs are
unaffected and continue to return the appropriate error status.
They just are no longer as chatty when doing so.
