drm/msm: Fix NULL deref in adreno_load_gpu
The msm/kms driver should work even if there is no GPU device specified
in DT. Currently, we get a NULL dereference crash in adreno_load_gpu
since the driver assumes that priv->gpu_pdev is non-NULL.
Perform an additional check on priv->gpu_pdev before trying to retrieve
the msm_gpu pointer from it.
v2: Incorporate Jordan's comments:
- Simplify the check to share the same error message.
- Use dev_err_once() to avoid an error message every time we open the
drm device fd.
Fixes: eec874ce5ff1 (drm/msm/adreno: load gpu at probe/bind time)
