[Qemu-devel] [PATCH v2] spice: Allow to set password even if disable-ticketing was used

[Christophe Fergeau <cfergeau@redhat.com>]

Before commit b1ea7b79e1, it was possible to start with -spice
disable-ticketing, and then use the "set_password spice" command to
enable ticketing with SPICE. Since commit b1ea7b79e1 this is no longer
possible as qemu_spice_set_ticket() will return an error unless the
'auth' type is "spice". When ticketing is disabled, 'auth' is "none" so
the attempt to set password fails.

This commit allows to call qemu_spice_set_ticket() when 'auth' is "none"
and changes 'auth' to "spice" when this happens.
