[apparmor] [patch] parser: fix warning in net_find_af_name

[Steve Beattie]

Hello,

The fix to prevent the compiler from SEGV'ing when dumping network
rules in commit 2888 introduced the following compiler warning:

  network.c: In function ‘const char* net_find_af_name(unsigned int)’:
  network.c:331:16: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
    for (i = 0; i < sizeof(network_mappings) / sizeof(*network_mappings); i++) {

The problem is that the counter i is an int, but sizeof returns size_t
which is unsigned. The following patch fixes the issue by converting the
type of i to size_t.
