netfilter: ipset: Fix range bug in hash:ip,port,net
Due to the missing ininitalization at adding/deleting entries, when
a plain_ip,port,net element was the object, multiple elements were
added/deleted instead. The bug came from the missing dangling
default initialization.
The error-prone default initialization is corrected in all hash:* types.
