[spice-server v3 02/14] qxl: Make red_{get, put}_drawable static

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Rather than needing to call red_drawable_new() and then initialize it
with red_get_drawable(), we can improve slightly red_drawable new so
that red_drawable_{new,ref,unref} is all which is used by code out of
red-parse-qxl.c.
