Subject[PATCH 3.2 01/46] Revert "ax25: add link layer header validation function"
3.2.81-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@decadent.org.uk>

This reverts commit 0954b59d9f4b2dcc59f28d1f64c3a21062a64372, which was
commit ea47781c26510e5d97f80f9aceafe9065bd5e3aa upstream. It is
pointless unless af_packet calls the new function.
