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.
