mm/shmem.c: fix unused shmem_parse_huge() function warning

When CONFIG_SYSFS is disabled but CONFIG_TMPFS is enabled, we get a
warning about shmem_parse_huge() never being called:

  mm/shmem.c:417:12: error: unused function 'shmem_parse_huge' [-Werror,-Wunused-function]
  static int shmem_parse_huge(const char *str)

Change the #ifdef so we no longer build this function in that configuration.
