nwfilter: Remove Coverity DEADCODE warning

The nwfilterStateInitialize() would only assign sysbus inside
a WITH_DBUS conditional, thus leaving a subsequent check for sysbus
and nwfilterDriverInstallDBusMatches() as a no-op

Rather than try to add WITH_DBUS conditions which ended up conflicting
with the usage of HAVE_FIREWALLD conditionals, just remove the WITH_DBUS
since virdbus.c has entry points for with and without conditions.
