accel/ivpu: Fix locking order in ivpu_job_submit

In the Linux kernel, the following vulnerability has been resolved:

accel/ivpu: Fix locking order in ivpu_job_submit

Fix deadlock in job submission and abort handling.
When a thread aborts currently executing jobs due to a fault,
it first locks the global lock protecting submitted_jobs (#1).

After the last job is destroyed, it proceeds to release the related context
and locks file_priv (#2). Meanwhile, in the job submission thread,
the file_priv lock (#2) is taken first, and then the submitted_jobs
lock (#1) is obtained when a job is added to the submitted jobs list.

       ----                    	       ----
  (for example due to a fault)         (jobs submissions keep coming)

  lock(&vdev->submitted_jobs_lock) #1
  ivpu_jobs_abort_all()
  job_destroy()
                                      lock(&file_priv->lock)           #2
                                      lock(&vdev->submitted_jobs_lock) #1
  file_priv_release()
  lock(&vdev->context_list_lock)
  lock(&file_priv->lock)           #2

This order of locking causes a deadlock. To resolve this issue,
change the order of locking in ivpu_job_submit().
