gpu: nvgpu: simplify nvgpu_timeout_init

Browse Source 
nvgpu_timeout_init() returns an error code only when the flags parameter
is invalid. There are very few possible values for flags, so extract the
two most common cases - cpu clock based and a retry based timeout - to
functions that cannot fail and thus return nothing. Adjust all callers
to use those, simplfying error handling quite a bit.
