Switch from using an sx lock to a mutex for the mac_portacl rule chain:
the sx lock was used previously because we might sleep allocating
additional memory by using auto-extending sbufs.  However, we no longer
do this, instead retaining the user-submitted rule string, so mutexes
can be used instead.  Annotate the reason for not using the sbuf-related
rule-to-string code with a comment.

Switch to using TAILQ_CONCAT() instead of manual list copying, as it's
O(1), reducing the rule replacement step under the mutex from O(2N) to
O(2).

Remove now uneeded vnode-related includes.
