This reverts commit 5b6155ee70, because
the block device ioctl's really aren't ready for it.
In particular, the "struct file *" and the "struct inode *" arguments do
not necessarily match, which means that the unlocked version of the
ioctl (that only gets a "struct file *") isn't actually able to handle
the cases it needs to handle.
