This broke the jail option (in some cases?) as the jail historically hasn't needed to exist at the time of rule parsing; jids will get stored and later applied. Fix this caller to attempt to parse *av as a number first and just use it as-is to match historical behavior. jail_getid(3) must still be used in order for name arguments to work, but it's strictly a fallback in case we weren't given a number.
