Murilo Opsfelder Araujo 79854b9544 block-qdict: Fix -Werror=maybe-uninitialized build failure
Building QEMU on Fedora 37 (Rawhide Prerelease) ppc64le failed with the
following error:

    $ ../configure --prefix=/usr/local/qemu-disabletcg --target-list=ppc-softmmu,ppc64-softmmu --disable-tcg --disable-linux-user
    ...
    $ make -j$(nproc)

    cc1: all warnings being treated as errors

Fix build failure by expanding the ternary operation.
Tested with `make check-unit` (the check-block-qdict test passed).
