Chances are that more devices with the mn8847x chips appear. Someone
somewhere might try to use this demod with the old dvb attach model
during development. Adding this memset will make the unload issue appear
all the time instead of randomly. But this patch doesn't really matter
so feel free to NACK it. I just wanted to post it for completeness.
I do think it is good practice to set pointers to null generally as that
would have saved me several days of work of whentracking down this bug.
The current dvb framework contain several other cases where pointers are
feed'd but not nulled.
