bcache: fix mistaken sysfs entry for io_error counter
commit 5461999848e0462c14f306a62923d22de820a59c upstream.
In bch_cached_dev_files[] from driver/md/bcache/sysfs.c, sysfs_errors is
incorrectly inserted in. The correct entry should be sysfs_io_errors.
This patch fixes the problem and now I/O errors of cached device can be
read from /sys/block/bcache<N>/bcache/io_errors.
Fixes: c7b7bd07404c5 ("bcache: add io_disable to struct cached_dev")
