ubifs: Export filesystem error counters
Not all ubifs filesystem errors are propagated to userspace.
Export bad magic, bad node and crc errors via sysfs. This allows userspace
to notice filesystem errors:
/sys/fs/ubifs/ubiX_Y/errors_magic
/sys/fs/ubifs/ubiX_Y/errors_node
/sys/fs/ubifs/ubiX_Y/errors_crc
The counters are reset to 0 with a remount.
