drm/fb-helper: fix input validation gaps in check_var
Apparently drivers need to check all this stuff themselves, which for
most things makes sense I guess. And for everything else we luck out,
because modern distros stopped supporting any other fbdev drivers than
drm ones and I really don't want to argue anymore about who needs to
check stuff. Therefore fixing all this just for drm fbdev emulation is
good enough.
Note that var->active is not set or validated. This is just control
flow for fbmem.c and needs to be validated in there as needed.
