mm: fix -Wmissing-prototypes warnings
We get two warnings when build kernel W=1: mm/shuffle.c:36:12: warning: no previous prototype for `shuffle_show' [-Wmissing-prototypes] mm/sparse.c:220:6: warning: no previous prototype for `subsection_mask_set' [-Wmissing-prototypes] Make the functions static to fix this.
