    tracing/trace_stack: fix the number of entries in the header · 083a63b4

    The last entry in the stack_dump_trace is ULONG_MAX, which is not
    a valid entry, but max_stack_trace.nr_entries has accounted for it.
    So when printing the header, we should decrease it by one.
    Before fix, print as following, for example:
    	Depth    Size   Location    (53 entries)	<--- should be 52
    	-----    ----   --------
      0)     3264     108   update_wall_time+0x4d5/0x9a0
     51)       80      80   syscall_call+0x7/0xb
       it's correct.
