[PATCH spice] worker: remove check for canvas during cursor connect

[Marc-André Lureau <marcandre.lureau@xxxxxxxxx>]

We want the cursor to be initialized even if there is no canvas,
especially when using a GL scanout. This solves some client warnings
when using qemu with GL scanout-only (patches under review on qemu ML).
