If dma_fence_wait fails to wait for a supplied in-fence in
msm_ioctl_gem_submit, make sure we release that in-fence.
Also remove this dma_fence_put() from the 'out' label.

Careful, we need to keep the put for the normal path. Maybe,
if (args->flags & MSM_SUBMIT_FENCE_FD_IN) {
struct dma_fence *in_fence;
in_fence = sync_file_get_fence(args->fence_fd); // keep line breaks natural
if (!in_fence)
return -EINVAL;
ret = 0;
if (!dma_fence_match_match_context(in_fence, ring->fctx->context)
ret = dma_fence_wait(in_fence, true);
dma_fence_put(in_fence);
if (ret)
return ret;
}
