Willem de Bruijn edb60bc7bb packet: validate variable length ll headers 
[ Upstream commit 9ed988cd59 ]

Replace link layer header validation check ll_header_truncate with
more generic dev_validate_header.

Validation based on hard_header_len incorrectly drops valid packets
in variable length protocols, such as AX25. dev_validate_header
calls header_ops.validate for such protocols to ensure correctness
below hard_header_len.

Fixes 9c7077622d ("packet: make packet_snd fail on len smaller than l2 header")
