chardev: add missing line break in pr_warn

To fix super long dmesg error lines like

  CHRDEV "dummy_stm.0" major number 224 goes below the dynamic allocation rangeCHRDEV "dummy_stm.1" major number 223 goes below the dynamic allocation rangeswapper: page allocation failure: order:8, mode:0x26040c0(GFP_KERNEL|__GFP_COMP|__GFP_NOTRACK)

After fix, it should look like

  CHRDEV "dummy_stm.0" major number 224 goes below the dynamic allocation range
  CHRDEV "dummy_stm.1" major number 223 goes below the dynamic allocation range
  swapper: page allocation failure: order:8, mode:0x26040c0(GFP_KERNEL|__GFP_COMP|__GFP_NOTRACK)
