Speculative fix for Surface strict mode crash.

Don't take ownership fo the local ref returned by
ANativeWindow_toSurface; just wrap it in a JavaParamRef to satisfy the
interface temporarily.

This is a speculative fix for the StrictMode crash; the introduction of
this Adopt appears to be the only functional change in the culprit CL,
so avoiding it might work; if so we can find a real solution afterward.
