nvgpu: reorder the check for same mask value

Browse Source 
After the board boots up, we have a specific set of settings for
each power mode which contains, fbp, tpc mask values, cpu, gpu
frequencies etc. So, we need to make sure to provide all the setting
values for each mode so that those will be applied correctly.
So, the fbp, tpc, gpc mask could be same in different power modes
and since the golden image context check which comes before is
returning -ENODEV, the nvpmodel service fails to set the power mode.

Thus, we need to compare whether the fbp and gpc mask values are same
before we check for the golden image context.
