Deepak Nibade 3c2656c8c6 gpu: nvgpu: clear events from channel/TSG while closing ...

If User does not close the event fd created on channel/TSG,
it is possible that the event stays on channel/TSG
structure and reappears when channel/TSG is re-opened

This causes false failure when we try to enable some event
of channel/TSG since we do not allow enabling same event
twice on same channel/TSG

Fix this by removing all enabled events from channel/TSG
while closing it
