gpu: nvgpu: allow suspend when jobs are pending
We currently check that no job is pending before proceeding with
suspend. This prevents suspend, when we could simply disable and
preempt all channels. Moreover, pending jobs accounting is done
using pm_runtime usage count, which is not updated for GPUs with
pm_runtime disabled (e.g. vgpu).
Replaced the check on pm_runtime usage count, with a check on
gk20a handle usage count. Suspend is allowed when there is no
task inside a busy/idle sequence.
