anv: avoid leaking private binding for aliased wsi image
Some checks are pending
macOS-CI / macOS-CI (dri) (push) Waiting to run
macOS-CI / macOS-CI (xlib) (push) Waiting to run

Aliased wsi image has to share the same private binding with the
original wsi image for memory consistency. If the private binding
exists, it needs to be released before being overridden.
