Deepak Nibade 2ac8c9729a gpu: nvgpu: make jobs_lock more fine grained ...

While processing all the jobs in gk20a_channel_clean_up_jobs(),
We currently acquire jobs_lock, traverse the list,
clean up the jobs, and then release the lock

But in this case we might hold the lock for too long
blocking the submit path

Hence make jobs_lock more fine grained by restricting
it for list accesses only
