Subject: [XFRM]: beet: fix worst case header_len calculation

The pskb_copy_expand crash I was seeing was triggered by BEET
mode not calculating the SA's header_len value for the worst
case, causing skb headroom expansions. This patch uses the
worst case value by including the maximum length of the pseudo
header.

The patch applies on top of the MTU optimization patch.
