seshendra 0214511e2e gpu: nvgpu: fix enable/disable fecs trace ...

- This patch fixes enable/disable fecs trace logic.
- Added enable_lock and enable_count to handle multiple
  enable/disable of fecs trace logic.
- If user does trace disable twice, enable_count will become
negative and when user tries to re-enable it, fecs trace
will not be enabled.
