[media] dvb_frontend: Use memdup_user() rather than duplicating its implementation
* Reuse existing functionality from memdup_user() instead of keeping
duplicate source code.
This issue was detected by using the Coccinelle software.
* Return directly if this copy operation failed.
* Replace the specification of data structures by pointer dereferences
to make the corresponding size determination a bit safer according to
the Linux coding style convention.
