[PATCH] kernel/panic: Do not append newline to the stack protector panic string

[Borislav Petkov <bp@alien8.de>]

From: Borislav Petkov <bp@suse.de>

... 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]  ]---
