fbdev: nvidia: Fix potential divide by zero
variable var->pixclock can be set by user. In case it
equals to zero, divide by zero would occur in nvidiafb_set_par.
Similar crashes have happened in other fbdev drivers. There
is no check and modification on var->pixclock along the call
chain to nvidia_check_var and nvidiafb_set_par. We believe it
could also be triggered in driver nvidia from user site.
