In v3dv_write_uniforms_wg_offsets() function, the job's cmd_buffer is a
valid command buffer, so there is no reason to check if its NULL or not.
This fixes CID#1487441 ("Dereference after null check") error.
v1:
- `job->cmd_buffer` is the same as `cmd_buffer` (Alejandro)
v2:
- Use `cmd_buffer` instead of `job->cmd_buffer` (Iago)
Fixes: 31a786c80a ("v3dv: handle QUNIFORM_FB_LAYERS")
