linux_ioctl_cdrom: reduce stack usage
... by moving two ~2KB structures from stack to heap allocation.
I experienced stack overflow in linux emulation on i386 (8K stack)
when LINUX_DVD_READ_STRUCT ioctl was performed on atapicam cd
device and there was an error that resulted in additional quite
heavy stack use in cam layer.
