Adrian Hunter 70df07838f perf header: Fix segfault on build_mem_topology() error path 
Do not increase the node count unless a node has been successfully read,
because it can lead to a segfault if an error occurs.

For example, if perf exceeds the open file limit in memory_node__read(),
which, on a test system, could be made to happen by setting the file limit
to exactly 32:

 Before:

  $ ulimit -n 32
  $ perf mem record --all-user -- sleep 1
  [ perf record: Woken up 1 times to write data ]
  failed: can't open memory sysfs data
  perf: Segmentation fault
  Obtained 14 stack frames.

  Segmentation fault (core dumped)

After:

  $ ulimit -n 32
  $ perf mem record --all-user -- sleep 1
  [ perf record: Woken up 1 times to write data ]
  failed: can't open memory sysfs data
  [ perf record: Captured and wrote 0.005 MB perf.data (11 samples) ]
