sv_main: Second part of fixing the MAX_ENT_LEAFS issue (after bumping MAX_ENT_LEAFS to 32 in r967).

Browse source 
If an entity is visilbe from MAX_ENT_LEAFS (32) or more leafs, don't try to vis-cull it, just send it to the client.
This should completely eliminate any flickering entities, no matter how many leafs they're visible from.

This could potentially increase packet sizes a bit.. but ent->num_leafs == 32 never happens in id1 epsiode 1, so it will not cause any increase on those maps.
hip1m1 has one entity (a rotator) that is caught by this change and will be always sent.
