O-Subject: [RHEL-7 qemu-kvm PATCH 1/1] spice: fix display initialization

Bugzilla: 974887

Spice has two display interface implementations:  One integrated into

the qxl graphics card, and one generic which can operate with every

qemu-emulated graphics card.

The generic one is activated in case spice is used without qxl.  The

logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes

unnoticed.  Fix that by adding a check in the spice interface

registration so we'll notice the qxl card no matter how it is created.
