Philip Elcan 7f8226887c gpu: nvgpu: cleanup return types for MISRA 10.3
This is a big cleanup of return types across a number of modules in the
nvgpu driver. Many functions were returning u32 but using negative
return codes. This is a MISRA 10.3 violation by assigning signed values
to a u32.

JIRA NVGPU-647
