gpu: nvgpu: fuse: return int for cal APIs

Browse Source 
The APIs read_vin_cal_slope_intercept_fuse() and
read_vin_cal_gain_offset_fuse() where prototyped for u32 return types,
but they were actually returning negative errno's for errors. Change the
return type to int so the errors can be checked properly.

clk_vin.c still stores the return values as u32's. This will be fixed in
a future patch.
