------------------------------------------------------
From: Dou Liyang <douly.fnst@xxxxxxxxxxxxxx>
Subject: mm: drop useless local parameters of __register_one_node()

__register_one_node() initializes local parameters "p_node" & "parent" for
register_node().

But, register_node() does not use them.

Remove the related code of "parent" node, cleanup __register_one_node()
and register_node().
