gpu: nvgpu: Use deterministic flag to decide pre-alloc

Browse Source 
Instead of using num_inflight_jobs to determine whether to pre-alloc
resources for a channel use the c->deterministic flag and the
number of inflight jobs field. Non-determinsitic channels do not
require pre-alloced resources and deterministic channels with 0
in flight jobs (i.e no kernel job tracking, AKA fast path sumits)
also do not require pre-alloced resources.
