kernel - Do not auto-destroy tap interfaces which are manually created

* When a tap interface is created via 'ifconfig tapN create' it
  will no longer be automatically destroyed on the last close.

* Previously could occur for tap units 4 or larger.

* Fixes unexpected ripouts of manually created interfaces, which
  can be particularly bad when the interface is used in a PF rule.
