[PATCH v4 02/18] spice: Update QXLInterface for spice >= 0.15.0

["Daniel P. Berrangé" <berrange@redhat.com>]

From: John Snow <jsnow@redhat.com>

spice updated the spelling (and arguments) of "attache_worker" in
0.15.0. Update QEMU to match, preventing -Wdeprecated-declarations
compilations from reporting build errors.
