Thomas Fleury cae5a0bc36 gpu: nvgpu: empty FECS buffer on trace enable ...

Currently, when reading from ctxsw device node, we are collecting
traces that occurred before enabling tracing. This is not wanted,
and makes testing unpredicatable.
This change drops existing data in FECS ring buffer when enabling
traces, as currently done on vm-server side.
