[PATCH -next] hwmon: (nzxt-smart2) Fix build with CONFIG_PM=n

[YueHaibing]

drivers/hwmon/nzxt-smart2.c:707:12: error: 'nzxt_smart2_hid_reset_resume' defined but not used [-Werror=unused-function]
  707 | static int nzxt_smart2_hid_reset_resume(struct hid_device *hdev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Move it into #ifdef block to fix this.
