[PATCH 3/4] perf kmem: Consistently use PRIu64 for printing u64 values

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Will Deacon <will.deacon@arm.com>

Building the perf tool for 32-bit ARM results in the following build
error due to a combination of an incorrect conversion specifier and
compiling with -Werror:

  builtin-kmem.c: In function ‘print_page_summary’:
  builtin-kmem.c:644:9: error: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘u64’ [-Werror=format=]
           nr_alloc_freed, (total_alloc_freed_bytes) / 1024);
           ^
  builtin-kmem.c:647:9: error: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘u64’ [-Werror=format=]
           (total_page_alloc_bytes - total_alloc_freed_bytes) / 1024);
           ^
  cc1: all warnings being treated as errors

This patch fixes the problem by consistently using PRIu64 for printing
out u64 values.
