gpu: nvgpu: implement sync refcounting
We currently free sync when we find job list empty
If aggressive_sync is set to true, we try to free
sync during channel unbind() call
But we rarely free sync from channel_unbind() call
since freeing it when job list is empty is
aggressive enough
Hence remove sync free code from channel_unbind()
Implement refcounting for sync:
- get a refcount while submitting a job (and
allocate sync if it is not allocated already)
- put a refcount while freeing the job
- if refcount==0 and if aggressive_sync_destroy is
set, free the sync
- if aggressive_sync_destroy is not set, we will
free the sync during channel close time
