[why]
Unlock is needed on the error handling path to prevent dead lock.
v3d_submit_cl_ioctl and v3d_submit_csd_ioctl is missing unlock.
[how]
Fix this by changing goto target on the error handling path. So
changing the goto to target an error handling path
that includes drm_gem_unlock reservations.
