Subject: compat_ioctl: fix block device compat ioctl regression

compat_ioctl: fix block device compat ioctl regression

The conversion of handlers to compat_blkdev_ioctl accidentally
disabled handling of most ioctl numbers on block devices because
of a typo. Fix the one line to enable it all again.
