gpu: nvgpu: do not flush FECS record on engine reset
Flushing timestamp record method can fail in case FECS is not processing the main method queue. In particular, this occurs in case of ctxsw timeout, where we process fifo sched interrupts from the host, but FECS is still waiting for idle (grWFI). In such scenario, this adds huge delay in fifo recovery procedure (timeout on FECS method). Since flushing the last (incomplete) record from FECS would only be useful in that case (context switch ongoing), remove flush operation on engine reset. Note that an explicit ENGINE_RESET event (with pid) is inserted in user-facing ctxsw buffer on engine reset.
