gpu: nvgpu: init: reduce CCM for nvgpu_prepare_poweroff

Browse Source 
Change how nvgpu_prepare_poweroff() handles multiple errors from the
unit poweroff functions. Previously, the last error was returned. It
doesn't really matter much which error is returned, just return an
error.

This update reduces the TCC metric from 11 to 8.
