[PATCH 2/2] drm/v3d: Release indirect CSD GEM reference on CPU job free

[Maíra Canal <mcanal@igalia.com>]

v3d_get_cpu_indirect_csd_params() takes a reference to the indirect BO via
drm_gem_object_lookup() and stashes it in cpu_job->indirect_csd.indirect,
but nothing on the CPU job teardown path ever drops that reference.

Drop the extra reference in v3d_cpu_job_free(). The NULL check covers ioctl
errors before the lookup ran and CPU job types other than
V3D_CPU_JOB_TYPE_INDIRECT_CSD, which leave the field zero-initialised.

Fixes: 18b8413b25b7 ("drm/v3d: Create a CPU job extension for a indirect CSD job")
