kernel/panic.c: do not append newline to the stack protector panic string

... because panic() itself already does this. Otherwise you have
line-broken trailer:

  [    1.836965] ---[ end Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in: pgd_alloc+0x29e/0x2a0
  [    1.836965]  ]---
