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.
