[PATCH 1/3 iptables] xshared: fix discards 'const' qualifier

[Rudi Heitbaum]

argv is passed by parse_change_counters_rule and do_parse to parse_rule_range
as a const char. parse_rule_range modifies thepassed in argv, so pass as
non const so that it can be modified without warning.

Fixes:
    iptables/xshared.c: In function 'parse_rule_range':
    iptables/xshared.c:912:23: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
      912 |         char *colon = strchr(argv, ':'), *buffer;
          |                       ^~~~~~
