[PATCH] udf: Mark LVID buffer as uptodate before marking it dirty

[Jan Kara <jack@suse.cz>]

When we hit EIO while writing LVID, the buffer uptodate bit is cleared.
This then results in an anoying warning from mark_buffer_dirty() when we
write the buffer again. So just set uptodate flag unconditionally.
