accel/ivpu: Fix locking order in ivpu_cmdq_destroy_ioctl
Fix deadlock caused by inversed locking order in ivpu_job_submit()
and ivpu_cmdq_destroy_ioctl(). Both functions operate locking
file_priv->lock and submitted_jobs_lock.
Unlock file_priv->lock in ivpu_cmdq_destroy_ioctl() before calling
ivpu_cmdq_abort_all_jobs() function which locks submitted_jobs_lock.
That way locking order is maintained:
1) global submitted_jobs_lock first
2) per context file_priv->lock second
