I don't think it should actually be a problem since bcache_unset_last_byte
checks for _last_byte_fd == fd. But, I think it's better to not rely on that
check, so how about a change like this?
void dev_unset_last_byte(struct device *dev)
{
if (dev->bcache_fd > 0)
bcache_unset_last_byte(scan_bcache, dev->bcache_fd);
}
