Deepak Nibade f7285577d7 gpu: nvgpu: enable wdt for each channel open ...

We currently enable per-channel wdt flag at channel
initialization time only

But if process disables channel's wdt via per-channel
IOCTL, and closes the channel without re-enabling it,
we leave the wdt disabled on that channel

And if same channel is assigned to some other process,
then that process might have wdt disabled already

Fix this by setting ch->wdt_enabled = true during
gk20a_open_new_channel()
