x86: Mark ptrace_get_debugreg() as static

This sparse warning:

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

triggers because ptrace_get_debugreg() is global but is only
used in a single .c file. change ptrace_get_debugreg() to
static to fix that - this also addresses the sparse warning.
