Remove rudiments of supporting procnum == 0 from 911e702077

Browse Source 
Early versions of opclass options patch uses zero support procedure as opclass
options procedure.  This commit removes rudiments of it, which were committed
in 911e702077.  Also, it implements correct handling of amoptsprocnum == 0.
