gpu: nvgpu: gk20a: add syncpt null checks
On channel_finish() path, we first check if last submit was
WFI and in that case we do not submit new WFI but just wait
on old syncpt fence.
But it is possible that sync resource is already freed from
another path (channel_suspend())
Hence add a NULL check there to prevent Null pointer
exception.
Also, in channel_free() path, move syncpt free API after
channel_unbind() since we logically free the syncpt after
unbinding the channel.
