Various block drivers implement the CDROMMULTISESSION, CDROM_GET_CAPABILITY, and CDROMEJECT ioctl commands, relying on the block layer to handle compat_ioctl mode for them. Move this into the drivers directly as a preparation for simplifying the block layer later. When only integer arguments or no arguments are passed, the same handler can be used for .ioctl and .compat_ioctl, and when only pointer arguments are passed, the newly added blkdev_compat_ptr_ioctl can be used.
