gpu: nvgpu: Return error code properly from nvgpu_vm_map_linux
The function nvgpu_vm_map_linux() used to return GPU VA on successful
map or 0 when things didn't go smoothly. However, this scheme does not
propagate the actual map error back to the userspace.
So, modify the function a bit: return error and return the GPU VA via
pointer on success.
