x86, mm: fault.c, remove #ifdef from do_page_fault()

Browse Source 
Impact: cleanup

do_page_fault() has this ugly #ifdef in its prototype:

  #ifdef CONFIG_X86_64
  asmlinkage
  #endif
  void __kprobes do_page_fault(struct pt_regs *regs, unsigned long error_code)

Replace it with 'dotraplinkage' which maps to exactly the above
construct: nothing on 32-bit and asmlinkage on 64-bit.
