[Qemu-devel] [PATCH 09/11] spice: use error_report to report errors

[Gerd Hoffmann <kraxel@redhat.com>]

From: Christophe Fergeau <cfergeau@redhat.com>

Error message reporting during spice startup wasn't consistent, it was done
with fprintf(stderr, "") but sometimes the message didn't have a trailing
\n. Using error_report make the intent of the message clearer and deal
with the final \n for us.
