Define struct spdk_bdev_io_error_stat privately in lib/bdev/bdev.c. Add a pointer to struct spdk_bdev_io_error_stat to struct spdk_bdev_io_stat. Allocate spdk_bdev_io_error_stat for bdev and RPC, but do not allocate spdk_bdev_io_error_stat for I/O channel. Dump the contents of spdk_bdev_io_error_stat only if its total is non-zero. As a result of these, only spdk_bdev_get_device_stat() can query spdk_bdev_io_error_stat for the bdev_get_iostat RPC. This will be acceptable.
