Subject: [PATCH] drm/v3d: Fix double free in gem code

These two patches fix the same issue:

- drm/v3d: Fix memory leak in v3d_submit_cl_ioctl (29cd13cfd76)
- drm/v3d: don't leak bin job if v3d_job_init fails (0d352a3a8a1)

And it seems that the conflict was missed during the merge.

Get rid of one of the free() calls.

Fixes: 77e0723bd27f ("Merge v5.4-rc7 into drm-next")
