msm: cpp: Complete compat handling of buffer delete call

When compat is used all IOCTL calls have compat handlers
which transfer data from 32 bit user space to 64bit kernel
space. After this transfer is done a new subdev call is
done with the 64bit data. To complete this subdev call all
IOCTL calls have to be listed.
