Fix build from -Werror=maybe-uninitialized.

This won't actually ever be uninitialized because the code will take a
failure path if the code that initializes it fails. The goto seems to
thwart this check though.

Not sure why this is only firing on userdebug builds yet. I'll look in
to it tomorrow.
