[PATCH -tip] x86: ptrace ptrace_get_debugreg() should be static

[Jaswinder Singh Rajput]

ptrace_get_debugreg() is used only by the same file, so it should be static.

Also fixed sparse warning :

  CHECK   arch/x86/kernel/ptrace.c
  arch/x86/kernel/ptrace.c:560:15: warning: symbol 'ptrace_get_debugreg' was not declared. Should it be static?
