When initializing a software smartcard, vcard_emul_init() can
report success, error, or indicate that initialization has already
been done. In this last case, we would assume that an error occurred
instead of behaving as if the initialization succeeded.
vcard_emul_init() can end up being called multiple time if the
smartcard channel gets destroyed and recreated during the lifetime
of the application
Fixes rhbz#815639
