acl-plugin: unapply the ACLs if interface is being deleted
(HC2VPP-137 is the client behavior triggering this)
If the user does not unapply the ACLs off the interface,
but deletes the interface, the subsequent reuse of the
sw_if_index might find itself with the datapath
hooked up for ACL processing even though there is
no ACL configured. The fix is to unapply any ACLs
in the callback which is called upon the sw_if_index
addition/deletion.
