tests/unit/test-block-iothread: fix maybe-uninitialized error on GCC 11
When building qemu with GCC 11, test-block-iothread produces the following
warning:
../tests/unit/test-block-iothread.c:148:11: error: ‘buf’ may be used
uninitialized [-Werror=maybe-uninitialized]
This is caused by buf[512] left uninitialized and passed to
bdrv_save_vmstate() that expects a const uint8_t *, so the compiler
assumes it will be read and expects the parameter to be initialized.
