mm, sparse: pass nid instead of pgdat to sparse_add_one_section()
commit 4e0d2e7ef14d9e1c900dac909db45263822b824f upstream.
Since the information needed in sparse_add_one_section() is node id to
allocate proper memory, it is not necessary to pass its pgdat.
This patch changes the prototype of sparse_add_one_section() to pass node
id directly. This is intended to reduce misleading that
sparse_add_one_section() would touch pgdat.
