Subject: [PATCH] gpgsm: Just print a note for an empty subject during import.

* sm/certchain.c (gpgsm_walk_cert_chain): Handle an empty subject.
--

During import a certificate was imported but gpgsm used log_error when
trying to figure out whether this is a root cert.  This patch changes
this to just print a note.
