memblock: fix section mismatch

allmodconfig produces following warning for me:

  WARNING: vmlinux.o(.text.unlikely+0x10314): Section mismatch in reference from the function movable_node_is_enabled() to the variable .meminit.data:movable_node_enabled
  The function movable_node_is_enabled() references
  the variable __meminitdata movable_node_enabled.
  This is often because movable_node_is_enabled lacks a __meminitdata
  annotation or the annotation of movable_node_enabled is wrong.

Let's mark the function with __meminit.  It fixes the warning.
