drm/imagination: Update the trace point pvr_job_submit_fw()

Browse Source 
Trace point pvr_job_submit_fw() is used to trace job submission to
the FW. Currently it is recorded when a command is written to the Client
circular buffer.

Move trace recording after writing command to the Kernel circular buffer to
better represent command submission to the FW.
