block/qapi: Clean up how we print to monitor or stdout
bdrv_snapshot_dump(), bdrv_image_info_specific_dump(), bdrv_image_info_dump() and their helpers take an fprintf()-like callback and a FILE * to pass to it. hmp.c passes monitor_printf() cast to fprintf_function and the current monitor cast to FILE *. qemu-img.c and qemu-io-cmds.c pass fprintf and stdout. The type-punning is technically undefined behaviour, but works in practice. Clean up: drop the callback, and call qemu_printf() instead.
