kernel/4.9: add missing newline character to UBI messages

A few UBI messages lacks the trailing newline character which
leads to ugly lines in the bootlog like this:

  [    6.649159] UBI error: no valid UBI magic found inside mtd6[    6.667751] Freeing unused kernel memory: 2196K

Add a newline character to the end of the messages to fix it.
After the fix the line from above looks better in the log:

  [    6.609182] UBI error: no valid UBI magic found inside mtd6
  [    6.627599] Freeing unused kernel memory: 2132K
