Fix two sparse warnings:
- atafb.c:1092: sparse: Using plain integer as NULL pointer

Use NULL instead of 0 when assigning a pointer.

- atafb.c:2824: sparse: switch with no cases

FBCMD_GET_CURRENTPAR and and FBCMD_SET_CURRENTPAR seem to be
historic defines, which are not any longer in the kernel, and
as such the code isn't built any longer and may be dropped.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
