[PATCH] drm/amdkfd: Remove logically dead code in kfd_procfs_show

[Gustavo A. R. Silva]

container_of is never null, so the null check on pdd is unnecessary.

If the null check is removed, function kfd_procfs_show()
will always return before reaching "return 0", hence
such return is logically dead. So, remove it, as well.
