isdn: hisax: Use l2headersize() instead of dup (and buggy) func.
There was a bug in my commit c978e7bb77dfd2cd3d1f547fa4e395cfe47f02b2
("hisax: Fix unchecked alloc_skb() return.")
One of the l2->flag checks is wrong.
Even worse it turns out I'm duplicating an existing function,
so use that instead.
