freedreno/pps: Fix multiple counter collection runs

Browse source 
The drm device file is closed and re-opened between perfetto traces.  So
we either need to re-create the fd_device, or use fd_device_new_dup() so
we hold on to our own fd.  The former is preferred so that the kernel
can realize when we are no longer reading the perfcntrs.
