tu: Reset rp_trace on tu_reset_cmd_buffer

Browse source 
Secondary command buffers with RENDER_PASS_CONTINUE_BIT don't reset
rp_trace, and without reset we get garbage tracepoints.

Fixes garbage sysmem_clear_all tracepoints in some games running
though DXVK.

Fixes: 630380349b ("tu: Give renderpass events a separate trace buffer")
