[PATCH] network: fix memory leak in networkAddFirewallRules()

[Elizaveta Tereshkina <etereshkina@xxxxxxxxxxxxx>]

Add g_clear_pointer() to networkAddFirewallRules()
after using virSetError() to free errInitV4 and errInitV6
to avoid memory leaks.

Fixes: ef760a4133 (Revert "network: support setting firewalld zone for bridge device of open networks")
