util: eliminate pointless switch in virFirewallApplyRule

Browse Source 
Since commit b19863640 both useful cases of the switch statement in
this function have made the same call (and the other/default case is
just an error that can never happen). Eliminate the switch to help
eliminate use of currentBackend.
