gpu: nvgpu: fix return type of *get_litter_value()
All callers for the *get_litter_value() functions were expecting u32,
but the functions were declared to return int's. This is a violation of
MISRA 10.3 which prohibits implicit assignment between essential types
(signed int and unsigned long int, in this case). The litter values
are all u32's anyway.
