gpu: nvgpu: set safe state for user managed syncpoints
MAX/threshold value of user managed syncpoint is not tracked by nvgpu
So if channel is reset by nvgpu there could be waiters still waiting on some
user syncpoint fence
Fix this by setting a large safe value to user managed syncpoint when aborting
the channel and when closing the channel
We right now increment the current value by 0x10000 which should be sufficient
to release any pending waiter
