Namhyung Kim c418d7a675 perf lock contention: Add a missing NULL check 
[ Upstream commit f3408580bac8ce5cd76e7391e529c0a22e7c7eb2 ]

I got a report for a failure in BPF verifier on a recent kernel with
perf lock contention command.  It checks task->sighand->siglock without
checking if sighand is NULL or not.  Let's add one.

  ; if (&curr->sighand->siglock == (void *)lock)
  265: (79) r1 = *(u64 *)(r0 +2624)     ; frame1: R0_w=trusted_ptr_task_struct(off=0,imm=0)
                                        ;         R1_w=rcu_ptr_or_null_sighand_struct(off=0,imm=0)
  266: (b7) r2 = 0                      ; frame1: R2_w=0
  267: (0f) r1 += r2
  R1 pointer arithmetic on rcu_ptr_or_null_ prohibited, null-check it first
  processed 164 insns (limit 1000000) max_states_per_insn 1 total_states 15 peak_states 15 mark_read 5
