gpu: nvgpu: clk: fix return type for vflookup()

Browse Source 
This changes the return type for the API fvlookup() from a u32 to an
int. The implementation of the API in vflookup_prob_1x_master() was
already trying to return negative values. This allows users of the API
to properly check the return value.
