The functions print_ipv4_addr() and print_ipv6_addr() are called with
string literals and do not modify these parameters internally.

Reported by clang:

    security/lsm_audit.c:324:7: warning: passing 'const char[6]' to parameter of type 'char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
      324 |                                                 "laddr", "lport");
          |                                                 ^~~~~~~
    security/lsm_audit.c:183:27: note: passing argument to parameter 'name1' here
