    powerpc/perf: Fix oops when kthread execs user process
    
    When a kthread calls call_usermodehelper() the steps are:
      1. allocate current->mm
      2. load_elf_binary()
      3. populate current->thread.regs
    
    While doing this, interrupts are not disabled. If there is a perf
    interrupt in the middle of this process (i.e. step 1 has completed
    but not yet reached to step 3) and if perf tries to read userspace
    regs, kernel oops with following log:
    
      Unable to handle kernel paging request for data at address 0x00000000
      Faulting instruction address: 0xc0000000000da0fc
      ...
      Call Trace:

      call_usermodehelper_exec_async+0x170/0x210
      ret_from_kernel_thread+0x5c/0x7c
    
    Fix it by setting abi to PERF_SAMPLE_REGS_ABI_NONE when userspace
    pt_regs are not set.
