Deepak Nibade d01a0249c4 gpu: nvgpu: cancel all wdt timeouts while handling SCHED errors ...

A SCHED error might cause multiple channels' watchdogs to trigger
simultaneously

Hence, to avoid this conflict cancel watchdog timeout on all
channels before recovering from SCHED errors

Also, define API gk20a_channel_timeout_stop_all_channels()
to cancel wdt timeout on all channels
