This patch checks if sk buffer is available to dererence ife header. If
not then NULL will returned to signal an malformed ife packet. This
avoids to crashing the kernel from outside.

There is currently no handling to check on a invalid tlv length. This
patch adds such handling to avoid killing the kernel with a malformed
ife packet.

This module is responsible for the ife encapsulation protocol
encode/decode logics. That module can:
- ife_encode: encode skb and reserve space for the ife meta header
- ife_decode: decode skb and extract the meta header size
- ife_tlv_meta_encode - encodes one tlv entry into the reserved ife
header space.
- ife_tlv_meta_decode - decodes one tlv entry from the packet
- ife_tlv_meta_next - advance to the next tlv
