perf record: Fix display of incorrect mmap pages

'mmap_pages' is 'unsigned int' not 'int' e.g.

  perf record -m2147483648 uname
  Permission error mapping pages.
  Consider increasing /proc/sys/kernel/perf_event_mlock_kb,
  or try again with a smaller value of -m/--mmap_pages.
  (current value: -2147483648)

Fixed:

  perf record -m2147483648 uname
  Permission error mapping pages.
  Consider increasing /proc/sys/kernel/perf_event_mlock_kb,
  or try again with a smaller value of -m/--mmap_pages.
  (current value: 2147483648)
