powerpc/mm: fix "section_base" set but not used



The commit 24b6d416 ("mm: pass the vmem_altmap to vmemmap_free")
removed a line in vmemmap_free(),

altmap = to_vmem_altmap((unsigned long) section_base);

but left a variable no longer used.

arch/powerpc/mm/init_64.c: In function 'vmemmap_free':
arch/powerpc/mm/init_64.c:277:16: error: variable 'section_base' set but
not used [-Werror=unused-but-set-variable]
