compat_ioctl: scsi: move ioctl handling into drivers
Each driver calling scsi_ioctl() gets an equivalent compat_ioctl()
handler that implements the same commands by calling scsi_compat_ioctl().
The scsi_cmd_ioctl() and scsi_cmd_blk_ioctl() functions are compatible
at this point, so any driver that calls those can do so for both native
and compat mode, with the argument passed through compat_ptr().
With this, we can remove the entries from fs/compat_ioctl.c. The new
code is larger, but should be easier to maintain and keep updated with
newly added commands.
