[PATCH liburing v4 1/3] tests/query: get rid of uninit struct warnings

[Pavel Begunkov <asml.silence@gmail.com>]

Compiling with -O0 revealed that compilers are too smart and complain
about io_uring_query_opcode not being initialised. It's not an issue as
it's passed to the kernel to be filled in, nevertheless, let's silence
the warnings.
