gpu: nvgpu: Base channel watchdog on gp_get

Instead of checking if a job is complete, only check that channel is
making progress by checking its gp_get is advancing.

This will make the watchdog conservative. Previously a whole job had
x seconds to complete. Now channel has x seconds to get host to
consume each push buffer segment.
