V4L/DVB (3809a): Remove compat stuff for DMX_GET_EVENT
The ioctl were removed by:
V4L/DVB (3727): Remove DMX_GET_EVENT and associated data structures
due to the ioctl DMX_GET_EVENT has never been implemented, and also
scrambling events can't be generated in a useful way by the hardware.
This patch removes the corresponding entry at fs/compat_ioctl.c
