mm: make copy_pte_range static again
commit 21bda264f4243f61dfcc485174055f12ad0530b4 upstream. Commit 71e3aac0724f ("thp: transparent hugepage core") adds copy_pte_range prototype to huge_mm.h. I'm not sure why (or if) this function have been used outside of memory.c, but it currently isn't. This patch makes copy_pte_range() static again.
