media: dvb_frontend: fix wrong cast in compat_ioctl
FE_GET_PROPERTY has always failed as following situations:
- Use compatible ioctl
- The array of 'struct dtv_property' has 2 or more items
This patch fixes wrong cast to a pointer 'struct dtv_property' from a
pointer of 2nd or after item of 'struct compat_dtv_property' array.
